Another ***** second hand car dealership

I purchased an Audi A3 from Monte Carlo Auto for my daughters first car, in February 2019 only to find a clucking noise on the front wheels. It was returned and some work was done on the brakes, we fetched the vehakle after a fiew days only to find the noise was wourse. Sounds like the brake pads are too small and are retteling in the calipers. My daughter is now too scared to drive the vehicle and a Mr Vasco (the sales person who sold us the vehicke) is avoiding us. He does not return our calls or E mails.
