Awful experience, put a deposit down on a car last...

Awful experience, put a deposit down on a car last Thursday, was told (in writing) that day the car was my mine and couldn't be sold. Heard from Brad ( the salesman) today telling me they sold the car on Saturday. I do not recommend this dealer at all, their word means nothing.

Hi Mike,
Last Thursday 7/5/18 I called Brad to place a deposit on the white "16 340 (a car I had spent months looking for hence why I was going out of state for the car), and I was under the belief that everything went smoothly. Brad took my credit card information and drivers license details and I was assured multiple times on the car was secured for me alone and that no one else could sell it (his words, I can show the text he sent me saying this). I filled out the BMW financial application to see if its rates were better than what I was getting for AAA, and sent a photo of my college diploma for the graduate program (note the sensitive information included in these documents like my social security number). I was told that we could arrange my trade in and time to pick up the car on Monday. So Monday comes around and I get a voice mail from Brad explaining that he was not in Saturday and someone had purchased my car. I was obviously confused because I had placed a large deposit to secure the car, and was told by Brad on the phone that the car was removed from the lot and had a "sold" sticker on it to prevent any one else from selling it. He explained that this happens sometimes (alarming to hear), and there was nothing he could do, and explained that a manager would get into contact with me. Later in the day I got into contact with Jim a manager at Devon and he explained that a deposit was never placed and even if it was they would not honor it and again I was told there was nothing they could do. This is alarming because I gave my credit card information to Brad on the phone on Thursday and was led to believe that my deposit was going through at that point. Jim also said that Brad was in on Saturday contradicting what Brad had said on his voice mail earlier in the day. I am obviously angry at the situation and confused based on the multiple stories, and was never offered any resolution. I asked if there was a similar model and Jim never bothered to check.
