Bias decision on account application

I app**** for an account at Jet which was declined. After a brilliant employee assist in a very professional manner, I was really positive about my application. Nobody communicated with me about the application. I am of the opinion that it was a bias decision. Yes I was sequestered but my rehabilitation was also done. I have since then got a vodacom account. I also co signed for my wife on an increase on a bond which was approved. I am of the opinion that if Jet personnel did just that little more they would be able to approve the application as I have the proof that I am credit worthy.
