Telkom Billing Disputes

The underground cable was damaged in a fire last year at the end of April beginning of May. I repeatedly ask them to fix the line as I was paying for a 10meg fast speed line and was getting less than a Meg on a good day or no service. I have been in dispute with Telkom since December over their billing and till today have not had any feed back at all. They now send me a bill for over R10 000 which is totally unacceptable as I have not had service since 8 December 2018. The only thing they took off was one call out fee. In February I told them to remove me off their system as I will no longer deal with them via the agents on email. Once again no feed back has ever been given. If you try phone them from a cell phone they keep you waiting for 30 minutes which costs a fortune. I am seriously sick and tired of Telkom
