Terrible service by Telkom

I have app**** for a Telkom LTE wireless. The device was delivered and two days later I cancelled the deal due to a medical emergency that came up and realised that I will not be able to afford it. I call the call centre on the 12/4/19 to cancel this deal and was assisted by Snethemba Ncobo who advised that she cancelled the deal. I asked for a reference number and was told by her to use her name as reference. Two days later and I still had not heard from Telkom to collect the device. I phoned the call centre again and spoke to Linda Ngshingila who advised it was not cancelled and that he will help me. I asked for a supervisor or mananger and was told they once again they are unavailable. I had to log another call with ref ********** 6 on 15/04/19. Still haven't heard from Telkom. Terribe service.
