cancellation issue

I write this with the utmost urgency! My frustration has peaked ,when I recently received a call from a debt collector on a canceled contract. I canceled the contract in June 2020 due to double debit order 2 months in the row. I gave back the SIM card in the store to the manager in the store at the time @telkom Kenilworth, however to my surprise Telkom attempted to pull money out of my account. I went to the store to make a second cancellation. I was assisted by Sino who emailed the head office, however nothing was done. Every month telkom attempted to do the same thing. Eventually I closed my bank account. I went back to the store. I was assisted by Qaasim Town. He sent an email to the head office after that I was not receiving any sms from Telkom . It came to my surprise last week when I received a call from debt collectors informing me that I owe telkom money , technically telkom owes me money. have all the documentation to prove this

Im typing this to get further assistance in the attempt to move forward
