Should i keep or cancel the phone

[stu9]

Just last Sunday i got an upgrade on 02 of an HTC One on a 24m contract, but after thinking about it I think i'm best to cancel it, as there's better things to do with £32 a month. It's a bloody good phone though, but just don't need it, basically it's £12 for the tariff and 20 for the phone. I did an online chat with them earleir and they said if that's what i want to do it's ok and just hand it in to a local shop. I want to keep it but like i say, £32 a month can be better spent saved/spent on other things
