Passing the buck to other department and account issue never gets resolved.

I have been trying to sort out a credit on my account since June 2021 Last year. I had overpaid the account and was in credit of over R8000 . In may the overpayment was zeroed for no reason. I continue to pay the account, .My account was suspended in December when i had stopped to make payment in October. In December the lady in the MTN legal department sent the recon to accounts to resolve. I am now siting in January 2022 and account is suspended again for the last two days . My experience they blame ever other department and never gets to the right person or department to fix the problem. Now they cannot activate my account as it with the technical department for the last 24 hours. The accounts have not rep**** to say they working on the problem issue sine today which is the issue that needs to fixed , so that they dont suspend my account.
