INFINITI of South Atlanta

Well today is June 26,2015 and I just purchased a Used 2012 Infiniti M37x. There was so much deception with this purchase that I really don't know where to begin. So lets start here. I previously owned a 2005 Infiniti G35x. I had started experiencing some mechanical issues with the car as a result of the axles breaking. So I ended up having my car towed up to infiniti for an diagnostic. After diagnosing the car I had a repair bill or 2$500+ dollars so I decided to look into getting a new car. I spoke with Andre Goolsby who seemed to be a fair and trustworthy person, as they all do. We went through a few options and after looking I decided on a 2012 M37x with 29000 miles on it. After going over the numbers with Andre I told him that I did not like the numbers that was presented. The deal was that they were giving me 3500 for a car that according to KBB was worth 4200 in rough condition and up to 8000 in great condition, $618 monthly payment and $2500 down. Well I didn't like that deal so I told him I would just get my car repaired. He later talked to me and told me not to pay the bill at that time but let them start the repairs and he would work it out. So the next 2 days I hear from Andre and He told me that they would give me $4500 for the car which sweetened the deal for me. He text me and told me not to come by at that time because he was trying to take care of the service bill that he said he would take care of. So finally he said to come on by. The first wrong thing was that the car we originally agreed upon was not the car he tried selling me. I had asked him what happened to the car and he said it was sold, and i had no clue. In addition the car had 55000+ miles on it and a different interior. I asked about it and he said that one was $3000 cheaper which was ok with me. Since im running out of characters to write more ill sum it all up. I end up having to pay a $2500 service fee for a car I sold to them and a down payment. The car was dirty on the inside and I didn't get the spare key. The icing on the cake is when he said that his dealership wont pay the bill because they dont want the care. Horrible job guys.
