TELKOM: SHOCKING SERVICE!

I went to the Fourway's Mall branch and cancelled my Telkom Mobile account on 10 August 2015, case number ***6. Telkom continued to debit my account on 3 occasions which resulted me in disputing these amounts and getting the debits reversed. I then went to the Fourway's Mall branch AGAIN to cancel my account on 03 February 2016, case number ***6, and they confirmed they had received my cancellation in August 2015. They could not give me an answer as to why my account was STILL being debited. I have since received a text message saying that I am 'in breach of contract due to unpaid debit orders.' I then phoned Telkom on 081 180 and spoke to Faith whom then confirmed she would cancel my account. I followed this up with ANOTHER visit to the Fourway's Mall branch on 11 February 2016 and spoke to Tau, who e-mailed the relevant persons and department with regards to cancelling my account. She said she would phone me back but has not since and I have just received ANOTHER text message saying that I am 'in breach of contract due to unpaid debit orders.' This is totally unacceptable. How many times does one need to cancel their account in order for it to be cancelled?
