Telkom cancellation

Cancellation!! Firstly, your online cancellation process is too complicated. I tried cancelling a wifi device, but the otp gets sent to the wifi sim unit, which I then first had to insert in another phone to enable my cancellation. Eventually did it online, had a technician call me to confirm that telkom has no connectivity in the area I am in and advised that it would now be referred to your cancellation department. I have heard nothing from them. I went into two stores for assistance, at the one, they just said they cannot help me. At the other, they mailed the escalation department, but i have had no feedback from them and cannot email them myself because mails get bounced back saying that I am not authorised to email the address!!! Come on Telkom, I am literally paying for a device I now cannot use because you do not have connectivity in my area!!! Assist your customers!
