Hi For the last six weeks the service from O2 has dropped so much in my home area that I am unable to make or receive any calls from inside or outside my home. I contacted O2 on twitter and then email about this at the start of August and they said that there had been other reports from O2 customers in the area as well. They said I needed to contact customer services along with anyone else experiencing issues, which I did. However each time I phoned or my flatmate phoned, as she was on O2 as well with the same problems, they said that there was no fault recorded with the mast. I have since dealt with their Senior Service Representative, Richard Chew, who credited two months line rental to my account. Fine, but I am still having problems and cant go on not being able to use my phone at home. They advised me to use TuGo, but I have the same problems on it and still miss all my calls. BTW their coverage checkers says good reception indoors and outdoors in my area despite this not being the case. They said that this is because they cannot find a fault with the mast. They have also insisted that I go into the O2 shop to get a diagnostics test done, which they cant do in the shop, to be told that there was no point as the issue was at my home address, and when I borrowed a phone to do it there was told that there was no point as it obviously wasnt my phone as it works elsewhere. Eventually they said that I could cancel my contract with no charge if I returned the phone. However, I am half way through a two year contract and feel that I have paid for half the phone, as well as the severe inconvenience and hassle that will come from me trying to wipe my phone of all personal data and contacts and setting this up on a new phone. As well as the costs of apps and inevitable loss of data/photos/music etc After further arguments they came back and said that their final offer was that I could cancel and keep the phone if I paid them £291, they say is a discount from £322. However, My monthly bill is £27, to pay for the next year including the allowances is £332. The O2 site says I can upgrade for £291 which is a discount of 25% line rental. This would value the line rental at £166, so I feel that I am being overcharged to keep the phone. Richard Chew has now said that there are no recorded faults with the masts and that is their final offer. He told me if I am unhappy to go outside O2. He said before that he will only review the case in 4 weeks, which if I cant use my phone is nowhere near urgent enough. I have said that I want payments suspended on the account while the complaint is pending and that I do not intend paying until it is resolved or accept any charges as a result of this, however O2 have not responded to this at all. I am worried that if I withhold payment they will mark my credit file as a default and possibly involve a debt collection company. I have referred to the ombudsman on this but I dont know how long this process will take and if O2 will mark defaults against me in the meantime. They have now effectively locked down, saying they have given their final response and thats it Where do I stand on this? Can they charge what they choose for me to cancel and keep my phone? Can they stop dealing with my queries because they have given a final response? Have I any rights in that the service I had 6 weeks ago at my home has gone and is now unusable? I am trying to decide if I am best handing back my phone to get out, paying over the odds to keep it or keep fighting the decision as O2 will not negotiate with me any more. I have spent an awful lot of time writing emails, phoning them and visiting their shops and cant afford the time to keep doing this. Any advise or examples of previous issues will be greatly appreciated Thanks Alastair Ps, I am currently trying to find my contract to see if there is anything about they providing service levels
