MTN Incompetence once again

I'm writing to express my frustration regarding a recent issue with my monthly debit order. My payment, which is supposed to be debited on the 25th of each month, did not go through in May for reasons that MTN has been unable to explain. Then, on the 12th of June, there was an attempt to debit my account again, which was unsuccessful. I do not keep extra funds in my account for unexpected mid-month debits.

I contacted your accounts division and received the following ticket number: REQ***23. However, I have not received any response, and my phone line is now at risk of being suspended. My account (11156BA***) is currently R 1,136.14 in arrears due to this issue, and this error is negatively impacting my credit report, despite it not being my fault.

I am extremely upset about this situation and would like immediate assistance to rectify it.

Thank you.
