******* Telkom Debits from my bank account

I got a Telkom router in 2020, and the contract was for 12-months only(Account number: ***) . I did not use it for the full 12-months as the network coverage was very bad in my area and for that I am also angry because I asked the consultant to check if there is network coverage in my area and she said yes there is. After the 12 months the contract was supposed to be complete, and I called Telkom and asked them to stop debiting my account . I was retrenched, so I owed them R1,600, but this amount was debited once I started working. They are still debiting R99 from my account, October 2022 they took R297 and this month, (November 2022) they debited R508.94 off my account. This contract has expired, and they have taken the amount that I owed them, so why are they still debiting my account, and when you try calling the call center you just don't get through to a consultant . The last consultant I spoke to asked if I want to continue with the service on a month-to-month basis and I told her NO! I don't even know where the simcard is. I did not approve the debits that are happening now and therefor they need to sop. Somebody needs to contact me to rectify this!
