Payment

Good day

I keep getting emails from MTN stating I have to make a payment, however, I canceled my contract and made an early payment.

Payment was made on the 28th of October 2020, however, i still get emails that i need to make payment.

Number in question: ***

Here are some of the references I have used to try call and get payments to clarify this issue: ***, ***, ***

This is so irritating as this matter has gone on for months and now my credit score is being affected.
