Impossible

Impossible ! they trying to make it impossible to cancel your contract as soon as they have you even if you 3 years run out. First they say 30 day notice then when you phone 30 days before as advise they say 20 day notice and you have to do it on the exact day. I just want to cancel my one contract *** you still have me on two other contracts so you will still make money out off me dont stress just cancel this one number!
