ABSA must be ****** because this makes no other sense.

I was pre approved for a vehicle. I had the score and the money and the only debt I have is a credit card with ABSA that I pay above what is considered the minimum payment. Thanks to ABSA, who I bank with, my credit score has dropped and now I cant risk going to another bank for financing. They promised to escalate it with there credit department since even the consultant didn't understand why I would be declined and credit department didn't give a reason for my application to be declined plus they assured me that I should meet the requirement. I was told they would investigate and come back to me. Its been 4 days, and I needed the car to travel to a funeral which I leave for tomorrow. I still have no resolution. I am starting to believe that the colour of your skin determines what kind of credit you receive in South Africa. I am in management position in my profession and work in 27 different territories and run a team all over the world. I earn in the top 5% in South Africa but I cant get financing from my own bank that accounts for only 45% of my annual net income? My Transunion score 681 and my total debt liability R13000 and no one at ABSA knows why I cannot receive financing for a R300000 Car? Besides race, why else?
