bad attetuite

I paid my account in in payments of R600, R510, R300,R160. Telkom said my account is paid in full. According to there policy it 48 hours to activate your line my line is off for 3 days. So the black female said im laying about the payments that I made I standing with the proof in my hands. She was ****** against me and sed she will not activate my line. That is how telkom is *****ing our money and all they can say eich sorry neh. Im paying for a service I dont have. Where can I complain. I want upper management to see this but they dont care about the customer as long as they get there millions of bonuses for doing nothing.
