Honda of Superstition Springs

OMG.. where do i start, this is my first time buying a car so i went in a little blind.! First, they wouldn't let me leave until i signed something i felt so pressured i caved. and just did it to leave then i went in the next day to check out the rest of the car. the guy doug was very nice, he showed me the car BUT then he passed me to Eddie he did the paper work. he said i only had to do 1,000 down, i did all the paper work, got insurance and everything, they told the car total was 10,000 including tax and titles, sale price was 8,450 so i was like ok that fine. So, i leave with my new car! very happy with the car and i loved the car. But then i went in a week later to 500 more down so my payments would lower, And oh my gosh, eddie sat me down and said he needed 1,500 more besides the 1,500 i already gave them or he was taking the car. so i told him i told have the money that i could give him 500 every two week when i get paid. he look at the computer he turned the computer so i could see it and said look the car is worth 7,000 and bank will only give you 9,200. so you have to put the rest down. then the price on the car said 11,118 and after taxes and stuff 12,somthing that's why they needed 3,00 down. so out of his own words he said " We were changing you to much" , I was just shoked and upset. i told i don't have the money. he said he need the keys. i was like okay but how do i get home. i ask can i take the car home tonight and drop it off tomorrow he said no. we will drop you off. i was just okay fine. the sad thing is i fill the tank before i went. and i ask will you give me my money back for filling the tank because it was only half filled when i took it. he said no. It's a week later they don't answer my phone calls and won't return my messages finally i had to have my mom call and she got the manager on the phone she told me we will call you when we finish the paper work then we will give you the difference. i talk to him on tuesday and it's now thursday still no call back about getting my downpayment back.. I you get a car there Be Very Careful they are [violative content deleted]! and i regret ever going there and i hope nobody will ever have to go through what i'm going through with them!
