Telkom suspension due to Telkom incompetency

I took out an unlimited data contract of 899 per month early last year. Telkom never deducts on the correct date and sometimes only every 2nd month. I have had to call in every month because of this for the past year and the price I'm paying is not even worth it as buffering starts after week 1 and as soon as more than 1 device is connected.

As soon as I make an EFT payment they will also deduct resulting in double payment. So they did not deduct in January 2021 and deducted double premium on 16 February after giving me over to collections due to their faults. Today on 28 February 2021 my wifi got suspended due to them not allocating the money to my account. I'm being told I can't contact a technical department and I have to wait for re-connection. I'm so frustrated with Telkom and can't even cancel my contract as I have to pay over R3000 cancellation. I wish my contract could just end so I don't have to deal with the frustrating side of buffering as well as incorrect monthly deductions.
