What an *********** network provider

I have been calling the *********** network for 3months now and still no answer to my query. I was given a few references and promised to be called back but it has been 3 months now. All I want is to cancel my contract with this *********** network provider and go to another network that values its customers. Kindly send me the amount that I need to pay in order to cancel my contract. I have been calling the call center but I cant get through. Word of advice to mtn, check how Vodacom is treating its customers, I have never had to struggle for anything with Vodacom for my other contract, they are always there to put a smile on the face of their customer.
