I Spent £41 on thier Huwei mobile broadband dongle with 3GB of date the downloads were quick all seemed well the only problem I watched one small not HD video on youtube for abour 5 mins then searched the the weather, recipes, etc and in 1 and a half hours my date was gone £41 worth of investment in my being able to enjoy the internet went up in smoke. 02 charges 20p per file per minute or whatever Beware, am now going to giff gaff or some one else I thought the dongle plus data was going to last at least 3 weeks as used to be when I was with 3 until they started to have problems with their data counter. How can 3 GB vanish over uploading ordinary web pages so quickly. Should have said on packet how they charge you for the 3Gb by the way this was not 4G speed either. My phone is with them and that has been good but am walking away from this!I feel ripped off and dont want to continue now either with their mobile phone service.I always thought they a better company!

I don't understand some of the bad reviews o2 get, I've NEVER had any problems with them, you get what you pay for with o2. The broadband speed has always been excellent, it's cheap compared to a lot of broadband providers and the customer care has always been there for me. Cant fault o2 in any way, only praise for them :)

Provided a very good service to me and I just renewed my contract with them for another few years.

I have been an o2 customer for over 10 years and have never had any issue with the service. On occasions when my phone has been lost or stolen, it has always been dealt with quickly and professionally.

I have to say i'm quite happy with 02! My whole family uses it and I'm quite haüppy to recommend it to my friends as well!

Rang o2 in May to cancel my O2 Broadband and phone package because Sky bought them due to bad experience with Sky service in the past to which they sent an email June " Sorry your leaving moving your broadband home phone to another company ... " . Yet now August 31 2013 they still send me an email monthly invoice for broadband home phone despite moving to another ISP in June for my phone broadband package, next invoice payment due 3 September,just so pleased that i cancelled my direct debit .

I recently moved house and expected it to be a right pain changing my account over. o2 handled it all for me, booked a date, sent me numerous emails to confirm and it all went through smoothly. no complaints.

Generally broadband was fine but after two years the service got slower. I upgraded to what O2 said was technically a better package for less than i was paying. The service was unstable and i was naturally unhappy, but became even more dissatisfied when i relised they had sold their service to Sky, they knew they were going to do this and obviously were trying to get their customers to sign up for a further 12 months at lowere prices so that they could sell their business to Sky. I signed up to be with O2, not Sky, so i left.

After 18 months of continual disconnection (approx once every hour) and repairing the connection to get a decent speed, I have finally decided to look elsewhere. Customer Services have been great and polite, whom I have contacted on various occasions, but long term does not solve the connection problem. This does not in any way relate to my computer as it is the service I believe according to the computer techs (had a full health check). I have broadband, landline and mobile account with 02, so I will contact the disconnection department very shortly. Who is the BEST broadband provider ???

I never felt so much frustrated dealing with a customer service, ever! I moved to a new flat and wanted to bring the broadband. After one month I spent so much money on calling O2 CS because they wouldn't call me back. Every time had to explain the whole story from scratch to someone who in the end wouldn't care at all. They couldn't solve a simple problem as identifying the correct line to take over (they were trying to take over my neughnour line in a 2 flat building!). In the end the only solution they would offer me was to cancel my contract. So frustrating you really can't imagine. Happy to move away from them.

I had been with O2 for my mobile for 5-6 years and had home broadband for 2 years, with no problems, that was until we moved house in December 2012. I called O2 explaining that we were going to be moving. I did say that I wasn't too happy with the £26 a month we were paying for home broadband and the home phone as we barely use either so said that because we were now moving then we 'may' cancel and go with another provider as I had found much cheaper deals. They told me that they could offer me half price line rental so that our total monthly bill would be £17 instead of £26, which I was happy to go along with. So this is where all the problems started.....we had to pay £42 for an engineer to install the line at the new house, which I was fine to pay, but they changed the date of the engineers visit twice leaving us without broadband and a phone line for longer than they orginally said. My partner and I both work full time so we arranged for our retired neighbour to let the engineer in to the house (they gave us a time frame odf 12-5pm which is ridiculous as they should be more specific). I spoke to someone from O2 and asked if it was okay for the neighbour to let the engineer in to the property, they said yes and suggested leaving a note on the door detailing this and also leave my mobile on so they could call if they had any problems. I left the note and my neighbour was in all day but didn't see anyone. A few days later I got an email saying that we had 'missed' our appointment and they were going to charge us £50. I was furious as you can imagine and immediately called them up and they apologised and said they would leave a note saying that we didn't have to pay the £50 charge. So the engineer finally made his visit and installed the line fine, I thought that was the end of it but it wasn't. A week later I got the bill through from O2 and they had charged me the £42 for the engineers visit but also the £50 charge for the 'missed appointment'. I called them up and spent about an hour on the phone where I was told that I would have to pay the charge of £50 because there were no notes on their system to say that we didn't have to pay it. I told them that my neighbour had been at home all day and hadn't seen an engineer, but he said that it was not okay for someone else to let the engineer in to the property, it had to be the account holder letting the engineer in. I told him that just a week before someone from O2 had advised me that it was perfectly fine for a neigbour to let them have access to the property and they suggested writing the note too. O2 completely contradict themselves because now I was being told that we the account holders had to physically be present at the property to let access for the engineer, and yet the installation had been carried out by my neighbour letting them in so it doesn't make any sense. It's an absolute joke that just because someone failed to make the notes (when they said that they would), meant that I was facing a £50 for something that was their fault in the first place because no engineer turned up!! I threatened to take the matter further because I was the one in the right and was no way going to pay the charge, so eventually they wavered the charge, which I was obviously glad about, but I've just received my latest bill which should now be £17 per month as they were going to cut my line rental in half, but my bill is for £28 (more than I was paying before!!) I called O2 again explaining that the only reason I took out another 12 month contract is because it was going to be reduced to £17, but yet again 'there are no notes on your account detailing a reduction in payment'. The only reason I decided to stay with O2 was because they were reducing my monthly contract and so now we've paid £42 for the engineer to come out, they have 'no knowledge' of a reduction in payment so were stuck paying more than we were paying before. I am beyond annoyed with all of the aggravation and stress this has caused so I'm going to call and cancel the whole thing, we're now £42 out of pocket for having the line installed in the first place. O2 are an absolutely joke and I would strongly advise anyone to steer well clear.
