ABSA trying to swindle me

So last year I wanted to switch bank and decided I'd apply for one with Absa, the initial application was done online which thereafter resulted being issued with the instruction to visit my nearest branch in order to complete my application and get my card. When I got to the branch ( Eastgate) I was welcomed by rude consultants who would not assist me when I inquired about the account number attached to the card issued, I wasn't even given any paperwork pertaining to the account- instead of being assisted professionally I was told that online applications are complicated and the only thing they could help me with was the card. Now I am being hounded by your call centre people over an overdue account, please explain the logic in that- how do you expect me to deposit monies and activate an account for which I was not given any account number? Please do not tarnish my name over you ineptitude. My next stop is the NCR because rest assured I will not dignify your incompetence with any form of payment.
