Unacceptable sales ethic

I was in the process of buying a car at InspectACar Gezina . There was some problems with the car that was agreed by them to be fixed before the purchase is complete. After confirming that I am buying the car, going through the process of getting financing approval and agreeing on the terms of the deal. I waited 4 days to hear from them to let me know what the status is regarding the repairs so I could activate the insurance and collect the car. After calling the salesman a few times with no answer. I manage to hear from him just to find out that the car was sold to someone else.
