Terrible Telkom

Where to begin? Cancelled an order for a Huawei B525 contract for 24 months I took up via MobileTalk. The cancellation was done within the 7 days cooling of period at the beginning of June 2019. The courier came to fetch the device and SIM. Still in June 2019, I confirmed via mail with MobileTalk if they received the device and that my contract will be cancelled, these were confirmed but to my surprise at the end of June 2019 I got billed for a device I had returned. I went to the Clearwater branch and was not assisted because apparently if you take a device via a call center (MobileTalk in my case) you won't be able to get assisted with any query by a walk in branch, you need to call the call center. Spend the beginning part of July going from pillar to post contacting MobileTalk at the end, they confirmed again that my contract was cancelled but still I got billed in July 2019. Went to a different Telkom store (Nicolway) and they assisted by calling the call center to log a query (***9). Its been 42 business days, that's roughly 336 working hours, weekly phone calls to the call center and still no resolution. But month on month I'm being charged for a device I have solid proof was returned to them.
