Absa Vehicle finance *********/unprofessional behaviour

It is shocking to say the least that my banker decided to change requirements wrt my vehicle finance application at Weelee. First it was approved with 0% deposit and decent interest rate, now ive received information that on 2nd thought Absa decided to add 10% deposit and 17% int (20% fixed). The reason as stated was my credit score dramatically changed. I must re-think doing business with Absa if they do not remedy this situation.
