damelin Pretoria is bad news :(

I registered for a course last year August , there was a special for that course (BAM) but I was charged more money than they promised when I went to query about it they kept on saying they'll fix it even today I keep receiving messages that my account is overdue ,I called their financial manager (magdeline nkana) n even sent her an email but it seems like they not willing to attend to my complain , and I need my results .
