Angry with MTN services

I am furious and so angry with MTN. I have a contract with MTN for almost 30 years. My last upgrade was Oct 2018. I pay my contract regularly each and every month at the end of the month. Now, all of a sudden from the end of last month, November 2020, am I a month behind with my account. They suspended my services and I had to go to the Riverside Boulevard branch to reactivate my services. MTN again suspended my services yesterday, 14th December 2020. Reason that I am all of the sudden 1 month behind with my premiums so I must pay another installment along with the end of last month's payment. I did so and my services were activated immediately. My services were suspended again this morning, 15th December 2020. No reason. My services are still not activated after 2 calls and 2 visits to the Riverside Boulevard branch........ It is nou 16:15.
