Ballon payment issues

Wesbank still hasn't come back to me regarding my ballon payment as I requested to pay a lesser amount Yes they call but I am not recieving any help , my calls are not returned My installment date is very near and I cannot afford it At this point, like they had said before , I am afraid they will take my car. Since then Maria has told me she's going to speak with her superior and till today she hasn't gotten back to me I called her yesterday she told me same story she is waiting for response. She promised me that she will call me beck yesterday before end of the day she didn't. I have to pay on the 10th which is Sunday so I am not sure how much must I pay because they told me that if I pay R2000 they will take it as money for arrears and is what I can afford.
