Very disappointed. I'v been on a contract with O2 for about 8 years or so, and I'm not getting a good deal compared to what's available now. Anyway, in an attempt to get a new handset (Motorola V3) and an identical tariff that is available on O2's website for new customer, I rang up to cancel my existing contract unless they agreed to match their own deal. To my suprise, they agreed to cancel the contract and said the only way I'd get that deal was to apply online. They did offer me a cheaper a handset, but I refused. The same deal is available from phones4u on o2with £80 cashback. General opinion seems to be that threatening to cancel prompts them to give spectacularly good deals in attempt to keep you. What did I do wrong to be turned away so easily? I've never missed a payment, and they've probably made a ton of money out of me over the years. Are phones4u any good?
