Supreme Ford Of Slidell

Bought a 2013 mustang gt, went test drive it and wouldn't go into 4th I decided to pass on the car until few weeks later they called me back and went test drove it and it was fixed bought the extended warranty threw them said if I sell or get rid of the car I could recover some of the money from the $1,800 extended warranty and they WILL NOT return my calls its been 3 months and still no word from them. Also when buying the car there was a little paint chip on the rear corner and they told me that if I buy the car today they could go wax and buff it to try and get it out and I told him the paint is gone and he argued that it might still buff out
