Prescribed Account

I would like to Log a complain about the account I have with Blakes Maphanga Attorneys. I would like to know why is my Balance shows as an Installment that I'm paying every Month not as Balance ,that is not the Installment I was paying ..I was paying R250 yet it appears as R2000 can that be fixed because that is giving me a Bad Credit Record. I would also like to find out why am I still listed because the account is PRESCRIBED and would like that to be sorted out, I Took that account in 2010 and in 2018 I couldn't continue paying till this year when they started sending me emails that I must pay an outstanding account yet account was already prescribed. I was Blaked Maphanga to remove my name from credit bureau as my account was prescribed a long time ago
