What A Rude/Pathetic/Poor Service I Received From Motshidisi

My account was in arrears with R839 in addition to the monthly installment and an arrangement was in place and they debited all the amount which was due to them, but right now I am getting surprises that my account is still active when I asked for a paid-up letter!!! This is really ridiculous!!!! You can't be telling me there's still an amount due whereas you debited my account. You can't be putting me at fault for your internal system errors!!!! I want my paid-up letter as a matter of urgency and should I not get any response before the closing of business today, I will have no choice but take this matter further. Firstly I'm gonna take it to social media, then NCR and the newspaper. I will also involve my legal team as well as the relevant authorities.
