Payment still not allocated after communication

Good day,<br> II had previously submitted a complaint to MTN stating that I had made payment on my account on the right day and at the right amount, and was told via email that it will be allocated and my outstanding account will be cleared. I assumed that the entry would be done simultaneously. However I checked my statement again for this month and yet again it reflects as outstanding by 2 months!<br> This is ridiculous for an accounts department to overlook!<br> <br> Please view your emails sent out and received and correctly allocate my prior payments.<br> This will ultimately affect my credit ratings so who is to blame when I have forwarded proof of payments and <br> you have failed to allocate as promised?<br> *** Cell number : ***
