Atrocious customer support

I’ve got an issue that I’ve been struggling with since July 2024,I made a payment to MTN settling my account after it being handed over to Nu Debt.

Unfortunately I used the MTN ABSA bank account for the payment with the NU DEBT reference. I have since struggled with getting a paid up letter or getting any type of assistance regarding this issue.

I’ve contacted MTN countless times, I’ve sent multiple emails to different employees at MTN who promise to assist, but until this very day, I have not received assistance. NuDebt is sending me post to pillar and MTN is blatantly ignoring me after I’ve sent my POP.

Now I’m being told that the debt I already settled, has accrued interest, HOW WHEN I SETTLED THE DEBT AS PER THE AMOUNT GIVEN TO ME BY NUDEBT???
