The contract term merely stipulates the period you cannot cancel without penalties. Beyond this date, the contract will continue until cancelled by the contract owner or until the contract owner ports out to another network. This will be laid out in the terms and conditions of the contract. I used to work for the mobile phone ombudsman and can tell you that you won't have a leg to stand on if you are looking for a refund of line rental for the unused months. Humphrey Bumphrey is right! Your best bet is to explain nicely to a team leader that you misunderstood the process. They may come to some agreement to partially refund some monies to you - but they have no obligation to do so! Oh and if you haven't already done so, cancel the contract immediately. Every day clocks up more line rental!
