TELKOM RIPT ME OFF!!!!

In Jan 2020 I accepted a telephonic contract with Telkom, for an amount of R700 with a FREE router and LIT Box ( TV Box). A few weeks later my line was installed and we were happy. My first debit order goes off and its an amount of R 2200.00, so I reverse the payment as if was going to affect my other debit orders. I go into the store and they correct my bill by crediting my account and I made a payment. They apologies and said they had incorrectly billed me for the TV Box. Month 2, the bill me incorrectly again, only this time there was no funds in my account, I was not able to go into a store to sort out so I do an eft for the correct amount and let it be. In the months to follow, they continue to bill and add interest and no one was able to assist me when I called the call center. I eventually go into the Game City store in Durban and drop off all my invoices, payments, reference numbers etc, never to hear from him again. Note, the TV box they supp**** me did not work and I had to return it, my line was blocked from further use, and i was still being billed, I don''t have a telephone at home an di was being billed for phone calls, UN F*#ken believable. I just couldn't deal with them any more so I gave up. I didn't have an internet service from them or a working TV Box. The internet line was faulty, which I reported. Why must I now pay Telkom R 11 000.00 when they have not given me a service. I WILL NOT PAY UNTIL THE BILL IS CORRECTED!!!!
