Telkom taking me for a ride and ripping me off

Morning. My experience with Telkom was up until my contract with them for a R79 modem ended. They started deducting random amounts from my account and no communications why.

We leave our contact details with them for a reason. I had to go to them in late September to ask why are they deducting money from my account whereas I didn't extend my contract with them, they told me I needed to fill in a form to close down my account and it takes 20 working days.

After many trips to the bank to reverse the money they deducted today in February their 20 days is still not over and they deducted R1033 for the very modem. Right now I need them to refund me with me doing a reversal and for them to stop going into my account without my authority. Capitec blocked them, they just come back later.

I am very disappointed in the way they do business. They did not even explain the process that towards the end I need to physically come and close this contract so they don't think this is important information. And taking money is someone's account is just fine. I am not happy with Telkom.

Please help me solve my problem
