incompetant ABSA bank staff

When my car was first financed by ABSA bank I was very happy. BUT then all changed. Their service got so bad that I decided to take my personal banking to FNB (not one bad minute from them). when my new account was opened I phoned ABSA to make the necessary changes for my car instalment to go down. <br> needles to say 3 months and numerous emails and phone calls later, after they made it look like my car instalment was never paid, I got it sorted eventually OR so I thought. now 7 months down the line, I can not get any bank to give me finance, BECAUSE of R3.27 that ABSA did not ask for initially. my instalment is on debit order, so naturally how would and account then be in arrears. NOW my ITC report looks like ****. Because of people work at ABSA that could not even pick up a Phone and ask if they could deduct the money or even to ask if I could pay it in. now for R3.27 I am *****ed. what do I stand to do.
