bad service

I app**** for a new credit card as I had lost the first one (which I had never used) I went into the branch to re-order my card - this was late last year sometime. Its February 2015 I still haven't received the new card nor did I get any feedback from anyone. I got a letter in the mail stating I owe them R1000.00 and my limit has been decreased because they did not receive any payment. The first card was supposed to go off on a debit order (they have my banking details) but it was never app**** to being debited from my account on ABSA's side. Now they are taking it to the credit beau to blacklist my name due to their mistakes of not installing the debit order. I phoned the branch, a lady said she will get back to me (this was 2 weeks ago) and I still haven't heard anything - phoned once more this morning and they transferred me to about 10 agents who still wasn't able to assist me. I cannot afford to have my name blacklisted now as well as paying the outstanding amount that I supposedly owe them. Please keep in mind I haven't used any of the cards but I need to make repayments?
