Non reply and bad service from Telkom after I cancelled my account

Sales Direct called me with and offer (Melissa Naidoo). She failed to inform me that the new router is not a migration, and that I will have to continue to pay my current router. I received the new router under the impression that it was a migration. When I phoned Telkom they informed me that I will have to continue to pay the old router as well as the new router. I completed their cancellation form and sent it to the in August 2017. After various calls to Telkom, Sales Direct, and the stores I still have the new router which I have not used and which I continue to pay.

I get no response form any telephone line
