I know this. I've rejected the offer of an exchange anyway.

UPDATE: Tesco Mobile's Technical Support team phoned me on Saturday 20th. They offered me an exchange, but not in the sense I expected. Instead of a brand-new phone it would have been an old one sent back to them by someone else. I refused the offer and stressed my wish to get out of the contract. Someone from their Customer Care team will be phoning me later today to discuss the matter. What can I say to get out of the contract without paying another penny? And what, if anything, can I do to get at least SOME of the money that I've paid them back?

No.

I've got a contract with Tesco Mobile which is due to expire in October. However, I want to get out of the contract early as I am unhappy with the service they are providing me. It all started when my mobile, an HTC Desire HD A9191, started acting up by randomly rebooting itself every few minutes. I sent it away for repairs and it came back to me some time later — but the fault hadn't been fixed. I sent it away again, and I got it back. It turned out to have been a waste of time, as the problem STILL persisted. I decided to use this when trying to get out of my contract. After all, I am paying £30 a month to use Tesco's services — and you'd think actually fixing the phone when it's faulty would be a part of that service. However, they flat out refused to let me get out of the contract without paying over £200 in remaining line rental, nor would they give me a refund. I'm at my wit's end here. Surely there is something I can do to get what I want?
