Cancellation nightmare

I have been trying to cancel this contract which I took up with JET for the past three years with no luck or follow up from agents, the customer service is not only terrible from both JET, VODACOM and RMCS when it comes to cancellation but their contracts will hold your number prisoner till you most probably die, there is no getting out of this so called contract. For the 100th time REMOVE MY NUMBER FROM YOUR COULD CONTRACT LIST.
