Pathetic service

In April 2021, I gave notice to MTN to please move over my contract which was on a month to month, to pay as you go. The callcenter indicated this will be resolved within a month. We are in August almost entering September and they are still debiting my bank account. I have emailed the retention department with the following MTN SA Reference Number: *** but still no response. It only makes me believe that MTN is now *****ing my money with no valid reason. The service has become pathetic and not sure how you conduct business. MTN, you level of service is pathetic and hope you are not *****ing other people's money as well.
