MTN Messes up my account and I must struggle

I upgraded my MTN account on the 15 November 2022.

There was some outstanding fees and I selected the option to have the outstanding balance broken down over a 3 month period. The guy in the shop selected this option for me.

On the 21 December 2022, the entire outstanding amount was deducted from my account. I reversed the debit order as that was not the agreement with MTN and I went into the store.

They explained that MTN had incorrectly debited my account and showed me that I had selected the 3 month option. They logged a ticket and advised it would be resolved. I paid for that month

On 3 January, my account was suspended and I phoned and they unsuspended it.

On my debit order date (20 Jan), again the full amount plus my monthly fee was debited. I reversed it again and went back to the store. The lady who assisted me said the original ticket was never escalated and she escalated it and said she would resolve it. I paid the monthly amount needed. She removed the debit order option on my account and made it cash so that the full amounts wouldn't be debited.

On the 3 Feb, my account was suspended yet again! I went back to the store, she unsuspended it and advised it was still being looked at. On the 20th Feb, I went to the store and paid in the store.

It is now the 1 March and my account has been suspended AGAIN! this is now ridiculous. You guys are not resolving my issue. You messed up with my payments. I had selected the 3 month option.

This needs to be resolved ASAP else I want to cancel my contract, you can have the phone back. Absolutely terrible service, would not recommend MTN.
