Poor unfair service

I want to sue Multichoice. We since paid the outstanding amount of R384.64 on 13th December 2020. But since then we have been disconnected 4 times, basically every week because some stupid somebody is too blind to allocate the eft payment that was made. They have added connection fees and penalties and now it has come a debt of about R1000.00. I'm sick and tired of multichoice, they are inconsiderate
