Triple Debit charge on MTN account on a monthly basis

We have had an account for over 21 years with MTN SA and havent experienced such bad service as we have experience until recently..........................

Our account had been debited 3 times in 1 month and every other month since February 2024 this year. whenever we try and use the account we are always blocked out. i have contacted MTN and went to their head office in Johannesburg and have had several meetings with Mellisa and she was supposed to log a query and to this day we haven't received our credit and our account is still not active. We reside in Namibia and we frequent South Africa a lot and require network provider its very frustrating. We have been trying to contact mellisa from Namibia via whatsap but there is no response from her as well.

can someone at MTN Pease reach out to us and sort this problem

regards
