Cadillac dealerships near me (San Angelo, TX)

Was told vehicle was in the shop for repairs on a shifting problem. Two days later they called and informed me that it was out of the shop and I could go by and test drive the vehicle. When I got there the car was in the shop for an A/C problem as well. When the mechanic went to test drive the vehicle after repairing the A/C he had problems with the automatic braking system while driving 70mph. Nobody in front of them or to the side. I am very disappointed in how they handled this potential sale.
