Telkom remove my name from the Credit Bureau. I don't owe you a cent and you know it.

Hello Peter, I m Maleshoane Gladys Thoahlane from LA Montagne Pretoria, I have a problem with Telkom in Menlyn Pretoria,I had a contract with them for two years it ended last year August,and I had written a letter letting them know I not going to renew my contract and they even responded that they received my mail To my surprise they a still sending me bills and took my name to the credit bureau,I went to the shop so many a time for them to check on my account unfortunately they haven't,and it has been taking more money from my account and always reversed ,it has been a long argument that I once involved the scorpion legal services they removed my name but now my name is back again,I m tired with Telkom don't know what to do.
