So I wanted to get an upgrade on my car, they took my car, charge me a down payment of 1200 dollars, let me leave with the new car for several days, and then they could not get the deal done, so they tell me I have to bring back the car today. After showing off this car to all my friends and family and loving it just to be told, I can not keep it and I have to bring it back. Yes, I understand they couldn't get the job done for whatever reason my credit or the banks wouldn't accept finance me., but to let me leave with the car for several days and to be told to bring it back because they could not close the deal, it's absolutely unacceptable. Not only is embarrassing it's was a complete waste of my time. I am very, very unhappy at the moment. I would have rather just been told, hey, we'll see what we can do and will let you know in a couple of days, instead of letting me leave with the car. Also I cut all my wires to my stereo system under the impression that this deal was going to go down and now I have to deal with that problem on top of everything else. I'm not sure if this is a normal thing that happens, but it is completely unacceptable to me.
