Since Dec 2014 I have suddenly been charge for DSL line that I have never app**** for nor have. 2 Calls and 2 visits to Telkom with each saying this is a mistake and \Sorry"and it will be sorted. Guess what????? Its Feb and I am still been charged???<br> <br> Telkom are *****! How dare you tell me one thing but carry on charging me and have the nerve to still slap a late payment charge?? <br> <br> Sort this out NOW TELKOM!!!!! or I cancel my line and Good luck getting any payment from me. And yes i will appear in court when you finally summons me!!<br> <br> *** - look up account"
