Contract cancellation nightmare

An absolute nightmare, I've been trying to cancel my contract since December last year and every time I call, no one has a reason why the consultant I last spoke to did not cancel my contract. I'm tired of calling them. They take forever to answer call or just end the call without even answering it. Kanti who is paying this contract ? Cant wait till my other contract comes to an end. Hopefully I wont have this problem. I will never refer anyone to vodacom. If u want a head ache, take a contract with vodacom
