Poor service from Telkom

I cancelled my Telkom line at your Vincent centre branch at the beginning of January 2020 as I have moved house. I requested that the cancellation happen immediately which I was told was possible. I was also told that I would receive a call from an agent and that the line would be cancelled within 24 hours. The agent never called and the usual line rental, which I expected was the cancellation fee, was deducted from my account at the end of January. At the start of February 2020 I again went to the branch to confirm that the line had been cancelled. The agent told me that the line was still active but that he would rectify the problem. He gave a *** and once again assured me that an agent would call to confirm. The agent never called and once again at the end of February the line rental has been deducted from my bank account. I would love an explanation as to why money is being deducted from my account for a service that I no longer use. I would also like confirmation that the line has indeed being cancelled. Lastly I want Telkom to repay the money that has been deducted. I look forward to a quick resolution to this problem.
