Disgusted and disappointed

I'm so disappointed in Capitec, I have been their loyal customer for so long but this is what they are doing to me now? I app**** for a loan somewhere around July 2018 I wanted to but a car and everything was fine loan was approved and they even offered me a credit which I also accepted, but after few days I realized that the money was not enough for the car I was looking for, so I went back to them within a few days and asked them to reverse it because I was then going to misuse it I told them I will try to push the existing and around November maybe I'll get a better offer, so I went back last week Wednesday to reapply because on the 22 November and I wanted a car. They say something went wrong when they were reversing the. Now they are making that my. They said I must give them some time they will contact me within 7 working, but nobody has done anything and I'm really frustrated at this because I need money.
