Payment allocation nightmare

I am really disappointed in MTN compatibility to allocate a payment that has been made on the 2nd of February 2025 from the same bank account I always use, using the same reference as always. Like literally nothing has changed. Yes, I paid a bit later than usual. Yes I paid an estimate that was about R200 short. But, for some reason they cannot allocate the payment when I have sent it to them multiple times. To many different MTN email addresses. Like how does a payment get lost that has literally the same credentials as every other month?? It's very stressful since my account has since been doubled in an outstanding amount of 4k, when I was just R200 short?? Make it make sense MTN. Up until today? You cannot allocate a payment with customer ID number as reference??
