Contracts Approved, waiting for Stock, and then suddenly = DECLINED

I app**** for a Contract at Telkom Online about 3 or 4 weeks ago, waited a few days for a Consultant to call me, the process just took forever so I decided to give Telkom Cape Gate a call. I wanted a Samsung S21 Ultra and then added a Samsung S21 Plus, everything went smooth, I worked with Damon who assisted me promptly, he gave me excellent customer service, Immediately worked on my application, within the same day he informed me all is in order and approved. The only problem was Stock. It is about a week later now and they are about to get stock in now anyday, when I contacted Damon today, he said that after everything and my APPROVAL, my approval status changed to declined and he cannot see why. I have a credit status of above 700, a good salary, everything was approved and I was just waiting for the Ultra to arrive, they actually have the plus in stock. I am not at all happy with this, he says there was a flag in some department and they cannot tell me what happened because he does not know. After weeks of this DRAGGED out process and now it is just declined with no reason?
