MTN suspends service for no reason

MTN suspended my services for no reason. Accounts are up to date. Next payment is due 17 January 2021 which I have paid in the interim.

They previously suspended my services for 2 weeks due to MTN updating their system and they did not link up old account numbers with new allocated account numbers with banks. It was a nightmare to get to the bottom of it and MTN staff was not trained to assist, FNB bank manager got to the bottom of the issue. Now again m6 services are suspended and I do not know why. I have emailed their customer service, escalation service and informed their Facebook team. No one has bothered to get in contact. My services are still suspended, it is now 2 days later. I have been a MTN customer since 2002. Very upset about this
