telkom over charging me

When I took out a contract with telkom I was so excited as I thought I was in safe hands since I had the worst experience with onether nertwork..little did I know that I was going for the worst.telkom has been over charging me and the worst thing is I reported this over and over again .fourways branch fixed the problem .two months down the line I was sitting with the same problem .telkom does not care about its customers ..I cant wait to cancel this contract honestly .will take my business somewhere else where my support will be much apreciated..and I will not let any of my family o friends have a contract with telkom.
