MTN DEBITING MY ACCOUNT WITH NO CAUSE

I wish to bring MTN's ineffective and ********** activities to light. I have 2 contracts with MTN, one is a cell subscription which was initiated in 2016, the other was initiated this year 2019. On numerous occasions I have called MTN to cancel one of the contracts and it turns out that I was upgraded without my consent as a result I am being charged at the end every month for a service I did not ask for.

I have called the customer care line multiple times and have been told that my query is being handled by the cancellation department. To date the debit order still goes off my bank account, the contract cancellation was requested in April. Four months later I continue paying for a service I DO NOT WANT. Can a representative from MTN please articulate the process for cancelling a contract? See below reference numbers that were obtained from the MTN Call center

Would appreciate MTN's response on this, no one seems to know how to cancel a contract! Thanks Lerato
