Pathetic Customer Service

I have been having issues with MTN since October 2020. They moved onto a new payment system in August 2020 and as a result some payments were not allocated to my account. I have had my account suspended every month since November 2020 and each time I call in, I send the consultant all my proof of payments, they note a "payment arrangement date" in order for my account to be immediately suspended and because the department who is supposed to be allocating the payments does not do their jobs properly, when the payment arrangement date arrives, my account gets suspended again. Then I have to call in and start the process again, but often I'm told they are offline. I am so frustrated with the pathetic customer service from MTN. If you read this and you are from MTN, please please do something to resolve this issue once and for all.
