TERRIBLE CUSTOMER SERVICE

I am so upset with the service I have received from my sales person, he portrays such a poor image of the Ford brand. I've been having such problems with my Fiesta ST which is by the way only 21days old. Gary actually has the audacity to say to me that I am getting excited for nothing because it's just wear and tear on the car. How is it possible to sell a car that has so many faults on it? What checks has this car been through? How do you speak to a customer like that? From the beginning all I have experienced was pathetic customer service from him and the only reason why I bought the car from Ford Fury William Nicol was because of the colour. He continued arguing with me over the phone saying that there is nothing he could have done to prevent this, the car breaks had 30percent life on them!!!! the oil filter was leaking!! The worst part was that he he never apologized, he carried on arguing with me and raising his voice. I don't know if he felt that because I am a women, he can speak to me any way he wants. I am so upset and disappointed, never have I experienced such pathetic customer service. He is a disgrace to Ford and needs to be take to task!
