Telkom

I need assistance with a problem I have with Telkom, our landline cables was ****** in August 2018, since then we had no landline, adsl or any service, on which I requested Telkom to cancel all services I had with them, in October 2019, they delivered a modem, sim card and cordless phone, which I did not ordered or asked for, I continuously send them emails and complained at the Springs Telkom shop, to cancel all. None of the services on the cordless phone or sim card was used, but they still send me an monthly invoice for the service which already mounted to over R8000.00. Up to date I had no assistance from Telkom in resolving the problem, Telkom are really bad with their customer service
