Debt

I have never been disgusted by such a company. I paid my account in 2024 with paid up letter only for them to come back 2 years letter saying I am in debt with them for an amount of the same amount that was paid. How stupid are they and they do not even take accountability. They made me pay extra R800 and when I phone MTN they told me I have fully paid and they did not submit my account again. I want nothing to do with MTN and their stupid collections team cause they delayed my debit orders, now I have to pay all my life just for a stupid R2000
