Be Aware of mtn Cell phone contracts

I am totally appauled by MTN contract phone offers . Firstly they billed me for so called wasp services which I so called registered for ( +- R1300 per month for 3 months). When I queried, it's apparently my fault. I was asked to cancel all the so called wasp subscriptions, which I have done but still being billed for. Secondly, why is MTN paying these services providers??? Is MTN part of this syndicate which robs millions of South African Customers??? Absolutely disgusted with MTN which includes the customer services
