No Response and Incorrect information

So recently i contacted ABSA to help me re-arrange my payment plan, so that I can try and get my vehicle paid up sooner. I have now contacted ABSA via phone and email, and tried every different option to get an answer, but I either don't get a response, or a get a completely incorrect response. I requested my instalments amounts based on a few different scenarios, and no one can give me an exact correct answer, how is it that no one at ABSA can assist me. all I get is NO Response, or completely the wrong information.

I don't understand why this is so difficult
