4 months to resolve an issue

Vodacom keep charging me for "content services" and Vodacom Live which I do not even know how to use. I logged a complaint and I am told to deal with their WASP (I am sure most people do not even know who/what this is). I contract with Vodacom so why must I deal with a WASP. Now they threaten to take action against non-payment but they have never resolved the problem. What other industry forces you to pay whilst they still owe you a credit????
