Unfair treatment from Vodacom

I got a quotation from Vodacom so that I can do a premature cancellation, which I paid on the 11th of May, I kept calling Vodacom, Consultants kept transferring me from pillar to post just to get my contract cancelled, some of them even dropped their lines the moment I mention "I would like to cancel my contract" why do they treat customers different when it comes to cancellation but always nice when we take contracts? Vodacom You need to learn to treat your customers fairly and with respect. lastly I spoke to Tricia who assured me the contract will be cancelled, though she did not have a Ref # for my call, at least she was the only person who was willing to assist me from Vodacom
