carmax deceptive practices, would not honor 5 day return policy,ruined my credit score jacksonville Florida

  I went to carmax since they had the vehicle i wanted. When i got there the car was gone.but i did accept an alternate vehicle. they ran my credit and wanted too much down. I am on disability,so saving money is difficult. they waould have new stuff, so keep looking, they said.

   I went in every other week to see what they had. and they ran my credit every time. I have to omit a lot of info as to not distract.It took 3 monthes to find a car, and then they said my credit had two many requests and it drug my score down.( they were the only ones who ran it, repeatedly every other week when i hoped to buy a car.)And the money toward my van went down by 100. I begged to speak with GM. who said he would do the loan but i must buy today.

   the sales man said " its late, lets run this car".but they needed me to pay my cable bill down. I needed til monday (from sat). all of a sudden they will hold a car for me.I went back mon and we closed the deal"bring it back within 5 days and we will put you in something else"  I now owned a 2007 caliber. no power anything, not even a cigarette lighter.Nothing about it.sunroof etc. 

   being disabled i wanted power everything,especially windows and seats. I simply wanted something I wanted.

   to cut it short. No exchange, and i now bought an 8ooo dollar car for 13000. We put the maintenance plan in there to drive the loan value up. 3.9 years later i still owe 12000 on it. because my score was down, i was hit with interest pretty hard.I went to try to trade it, and the salesman really verbally pounded me until he found out i bought it there. then he called his manager and disappeared. the manager said i was too upside down.. I would need about 5 or 6 thousand down.

  oh yeah, the original salesman told me "pay for a year or so on time and get your score, then santander will refi for you".. after 16 monthes i talked to them about that, and they told me that they NEVER refi their own loan.. So i still pay my 373 a month and pray for the lottery.

   is there anyone out there who may have a similar story, i understand that a civil suit is not out of the question.  Thanx for reading.  about the credit card usage, they absolutely would not accept a cr card or a check.
