Jan 31,2025Aftab seemed to be the only advisor showing any empathy with my dissatisfaction. I am a loyal Onecom customer who wanted to renew my mobile contract. No one from Onecom reminded me in September I needed to renew my discount and consequently my monthly payment increased from £20 per month to £62:20 per month. As a result I paid £62:20 for 3 months and then it increased to £72:20 in January 2025 ! I discovered that Onecom had also added a further £10 per month for cyber protection I had not asked for ! When I contacted Onecom they agreed to discount the charge for cyber protection. Consequently I renewed my contract for 3years at £17:40 per month. Sadly I noticed on the 27th January an invoice for £135. I couldn’t believe it ! I called Onecom to discover they claimed I had called them to renew my contract on a premium 08 number and that’s why I had a bill for £135. I telephoned on a number for Onecom I had googled and got through to them. They accepted I had spoken to their advisor Andrew on this number to renew my contract which took 1 hour 35 minutes. I had to call Onecom several times to complain about this charge being removed. The first advisor promised to call me back and didn’t. Aftad in fairness did call me back and said as a measure of goodwill the company would refund £65. Not at all impressed with Onecom if this is how they treat loyal customers who renew mobile contracts with them !!! Aftad the only customer advisor who displayed any compassion or understanding at all. What does this say about any sense of goodwill from Onecom !!! Absolutely outrageous !!!!!!!!!!

Jan 30,2025I am using OneCom for Internet. The performance has been very poor with a download speed of 2 Megs out of a 20mb/s for £89 per month. After trying to contact support 3 times and them hanging up before I got through, I finally switched. They reduced the bandwidth down to 0.25Mb/s and upload of 0.15Mb/s even though we were still paying full cost. When I complained they told me "As services are getting disconnected hence it might affected the speed".

Jan 30,2025I was approached by Gareth Duggan through this company about a new business phone contact over around an 8 month period and genuinely thought he was trust worthy... turns out he's just another salesman who couldn't care less about other people's finances (especially over Christmas) and only the numbers that he makes for this business. I was told my termination fee (from Plan.com) would be covered by Gareth (which it only came to around half of the final invoice fee) and then 45 days down the line I was then contacted by a debt collection company stating that I owed another £415 to another company (prestige telecom) I have emailed Gareth twice now with no response at all, now he's got my money for 36 months he's not interested and he also sold one of my phones through a 3rd party and I got less that half of what he told me I would get. With all this happening over Christmas, had I have know what the true cost of this would have been, i would not have renewed my contract and waited for it to run out... I feel that Gareth has been absolutely disloyal about the true picture of this and has not made any efforts at all to try and help in any way. Moral of the story is to avoid this company especially if Gareth Duggan is on the end of the line. Totally ruined our finances this Christmas for our family.

Jan 30,2025If I could rate no stars I would. This company have been nothing but painful to deal with! They signed me up to a 3year contract when (I was caught off guard) I had mentioned, I was traveling home and whether they could call back later, did they, hell no! They hard sold me two lines for a reasonable price, (or so I thought) but wait, it gets better not only does this particular provider(vodafone) does not unfortunately for me, provide much signal where I'm based but it turns out for the work location, it too hasn't got great connection!! When on the phone with onecom, they assure me they do. Little did I know they were royally screwing me. I later checked the signal online and walked into a shop and they showed me, they in fact DONOT cover my area! (by this point I was stuck in my contract for three years with onecom, they never did try to resolve this issue! Thanks Onecom! Anyway, when it came to payment they assured me it would be 42.00. When the DD started to come out if the account, they took double the amount which I though was odd! When I rung them they said, "oh don't worry, we will transfer the difference each month. What a rather odd system!!! After a year of back and forth being put on hold, passed around to different call handlers, I had the final straw and requested for someone to reinburse me for being charged an extra 50.00 this month with no warning! The person I was supposed to speak with was busy at this particular time I had called, I was reassured that this person would call back within 15 mins. When I sat by my phone waiting for 30mins and still no call back. I called them to find out that the centre had closed. Surprise surprise!! I decided to call back the following day, I was informed that they had tried to call me back but they couldn't get through. I said, oh so you are admitting that after a year my line has signal issues!!!! Either that or you are lying about calling me back, which one is it? I got no further with my enquiries! This company is a huge scam and I advise you all to keep clear!!!!!

Jan 29,2025Archaic business practices. Completely inflexible and using bait and switch tactics. The initial pitch is to pay off the contract remaining with your current provider, sell you on some extra services and then get you in a 36 month contract. What they have so carefully crafted into their sales pitch is a quiet word about the 17 month discount they apply and that is waived away by saying they will get a renewed contract with the same discounts arranged at the 17 month mark... it never happens. A tariff review amounts to about £5 off any line you have, while they are charging astronomical amounts for terrible service. I can see how they could be a really useful company to larger businesses but they should not target small businesses with limited use for their services. They have airtight contracts, no exit clauses and no flexibility for changes to business circumstances. Heartless is probably a little too nice for them. They know exactly what they are doing in the initial sales pitches, know the profit they will get with each sucker they get in for the 36 month contract, and the manner they speak on the phone about it is the most frustrating part. They do exactly enough to ensure the CISAS rulings go in their favour. Good solicitors, terrible ethics.

Jan 28,2025PLEASE PLEASE PLEASE do not get sucked into a contract by this company, 3 year contract with big inflated amount with only 2 years credit back So vodafone charge £100 then these credit you £80, So when vodafone hikes the price up each year you contract in effect doubles as they are adding 10% to £100 and the credit stays the same, I am now in my 3rd year paying £150 per month for a contract i can get for £8 per month And now they decide to add another product to my bill at £10 a month without my consent and are trying not to refund me absolute scammers.

Jan 27,2025Leaving one.com is a nightmare. I have never done something so difficult. My domain is still not transferred; they have reregistered it and charged me. They are expensive after you sign up (a year later). Expect to get support in two days.

Jan 25,2025Most of the 5star Reviews are fake, this company is a scam - Our entertainment packages were down for 6 months and we received no compensation or explanation of why; we were explicitly told that the wifi boxes were free and would not incur a cost. (We had made this extremely clear that we do not want them if they’re to incur a charge). After the 17/18 months of our 3 year contract they began charging us for these, bringing our total to £200 per month for 1 phone and 2 SIM cards… (We’d never even opened the wifi boxes and they’re now trying to charge us one final payment AFTER our contract has expired because it takes them 30 days to shut them down) WE NEVER EVEN USED THEM THE ENTIRE LENGTH OF THE CONTRACT!!!! Spend hours upon hours on the phone to the most incompetent staff that bold face lie on the phone - Like we have, I’d advice if you have been tricked into a contract with these scammers, RECORD EVERY INTERACTION YOU HAVE WITH THEM, Trust me! Onecom And Vodafone need investigating! Avoid, Avoid, Avoid.

Jan 22,2025Added a cyber security service to my broadband service without even asking if I would like it now won’t refund the extra charges. And won’t let me cancel without paying £1400 as they also like to tie you in for 3 year contract. Avoid at all cost this rip off company

Jan 21,2025I’m Very Unhappy with onecom! By far this is the worst service I’ve ever had! Sales woman promises so much and it’s been a complete disaster of incompetence! I received my new phone on the 17/01/25 and it still is connected! Who knows how many customers I’ve lost due to them not being able to call me! They are not open at weekends! So I had to wait until today to message them on what’s app and at 8.30am they said my live data was missing and said I would be connected in 2-3 hours! 5.30pm I’m still not connected!! I what’s app them again and they say on telephone it takes 10 seconds to connect but 40 minutes later I’m still waiting for a reply! I’ve now emailed, phoned and what’s app all day and still I’ve no connection! Disgusting Service!!! Date of experience: 21 January 2025

Jan 20,2025Scamming liars false advertising and giving false information to get you to buy into their services u don't need then when u question it they tell you to refer back to the contract they tricked u into signing then refuse to listen to their fraudulent phone conversations

Jan 18,2025Incompetent, thieving rob-dogs!!! My so called contract went up from £40 to over £150/month. To add insult to injury - their customer service is appalling!!! Don’t touch them with a barge poll. That also goes for their partners-in-crime ‘VODAFONE’!

Jan 18,2025If you don't renew your contract for 2 years they will fleece you, don't go near them there are loads of companies out there who won't, they also added a 2gb of data sim card and charged me an extra £12 a month which I didn't want or ask for, why would anybody pay £12 a month for 2gb of data on a contract, they think you won't notice it. If anyone wants to view my contract I will make it available

Jan 17,2025I have been with Onecom for a month now and am really disappointed with the service. I (perhaps naively) thought I was signing up for a service where I would just receive calls made to my landline on my mobile number - That's how it was sold to me. Instead I have been presented with a complicated system that uses three different websites - none of which were explained to me, and all of which appear to be designed for companies with large numbers of employees. For the last month I have not been able to receive calls made from landlines despite repeated support requests. The Webex app that I use on my mobile phone often rings but I can't find a way to answer it and I also don't seem to be able to listen to my voicemails on it. The whole experience has been frustrating.
