Telkom Cancellation nearly impossible

If you can help it, don't ever do business with Telkom. It is nearly impossible to cancel service with them. I gave notice on 12 January 2021 to cancel my ADSL as I moved house. They made me pay three months subscription, claiming that is how it works, even though they have a 30 day notice period. And they blacklist you if you do not pay. On top of that, they *******ly activated TWO mobile contracts on my account end of 2020, and I wasn't even in the Country at that time! Debit order and all. Terrible service from a company that used to be great.
