Bad service that affects the client negatively

Just to open an account took me 2full hours and to my surprise on pay day my debit orders were not switched as the consultant assisting me informed after completing a debit order switch form in the branch. I am now owing my previous bank for unpaid megtape charges estimated 1800 of which fnb Pavillion is saying I did not report in time. Surprisingly very same branch take a week to 2 weeks to come back after I had raised the matter with them. It's been a full month I have reported the matter to the consultant at the branch but I must say their turnaround time to resolve matters is ridiculously long.
