Poor Account handling

MTN is at it again with me-This feels like it's becoming personal.

Last week I received a call that my account is in arrears. Explained to the consultant that I made payment and received confirmation from MTN stating this. I checked the MTN app and it showed that the payment i made was not reflecting. I forwarded the MTN confirmation to their customer care and they responded yesterday with the following:

Good day Sir/Madam,

Thank you for your email.

Please note that the payment that you made was received and allocated to your account BA***, but however your account BA*** is still in arrears with an amount of R2395.60.

We trust that you find the above in order.

Warm Regards,

Now my account is in arrears due to them catching on nonsense and the money is on my other account that has a debit instruction. I would like MTN to fix this mess ASAP as they caused my account to go into arrears.
