ABSA VEHICLE ASSET FINANCE IS AWFUL!!!

I have been having constant problems with ABSA VEHICLE ASSET FINANCE for the past year. They debit my account on the wrong dates and give me the same robotic responses every time I query this for correction. I've been complaining for about a year and nothing is done, the consultants are rude and frustrate the entire process. I have never had such issues and had my vehicle previously financed by them without problems but I can't take this anymore. They seem to be completely useless at resolving a straightforward issue.
