Unauthorized debit order

I m so disappointed, how my case have been handled. I had a contract with telkom for 3yrs and paid it in full up to 36 months as agreement. And that was September 2025. Before my contract ended I went in September to make sure that I will not be paying anything write after. I was to told to come back after my last day of the contract. I went to the nearest telkom again after I have been told to wait until then. They called their customer care to do the cancelation. I was told the store cannot do cancelation, They will have to contact their customer care. I waited while they were busy. Then I was told is been canceled. I was puzzled when telkom continued to deduct money from my account for the next month's. Which is Oct, Nov and Dec. I have called their customer care so many times to fix this and the dedit still continue to date. My insurance was canceled and I was sent a confirmation and now telkom is failing to take this matter seriously. I have told them that I m not working and they talking every cent my kids must have for Xmas. All I need is my money back. And I will never ever recommend or even have any deals with Telkom. And I wish people will stop having contracts with them. If this matter is not resolved. You are giving me no choice but to take further steps.
