I need to get out of this contract, i dont have a job to pay the remainder of the bill, and in November i will not even be in the country and i will therefore no longer need the phone or the contract anyway!!!!!
What I think you should do is write to the Orange Customer Service Manager, explaining your circumstances and see if you can come to an amicable arrangement.
I am sure Orange would not want the hassle and expense of chasing you for a debt, which they are unlikely to recover, if you moved abroad and they could not trace you. Orange would end up selling your debt to a debt collection company for a fraction (say 10% of amount owed) and you would have a default on your credit record.
It is in your interest to settle the matter before you leave, as I am sure you would not want to leave behind a damaged credit record. Such a default could cause you a problem if you ever returned to the UK and needed any credit or financial product.
