Unfair - Paying for something you not going to get

So I want to cancel my contract with them and ask for a quotation and on that quototation i noticed that i would have to pay for airtime i will not be getting so i find that very ********* and unfair, it's just a way for them to force people in to staying on the contract when a person clearly doesnt want to anymore.<br> <br> Never will i take up another contract with VODACOM again!!!!
