Lonestar Auto Center

Lonestar posted a set of BMW tires and rims for sale on Craigslist. I spoke to Andre the mechanic on the phone and asked him several questions about the Rims including if the tires were good and if they had the BMW sensors that relay tire pressure info to the car computer. These were important to me because if you dont have the sensors, you cant tell if you have a flat. The posting said the tires were «85%» and I was told the wheels were «like new».
When I got there I noticed the rims were not in the condition they advertised and I asked for a price adjustment as it was perfectly clear the wheels were not like new as advertised. Tony, the owner or GM, started berading me for asking for a price adjustment and that the rims would cost $ 1600 at the dealer. I am not an expert in tires so after some time I agreed to buy the tires and rims and paid cash to Tony, the owner/​GM.
Tony agreed to mount the mount the wheels on for me and Andre performed the work on site. After a few days, the right rear tire ran a flat. I towed it to a gas station, replaced the valve, patched the tire and during that process realized that the tires did NOT have the sensors that they said they would. Had they had the sensors, I would have known that the tire was leaking and could have pulled over to safety. After another day, the left rear tire blew to shreds and I almost crashed with my fiancée in the car. I called a tow and the tow guy said all 4 tires were dry rotted and no dealer should have mounted these or sold them… the tires were very dangerous. Not only were the tires dry rotted, they had «knots that were about to blow». I did not know what dry rot was until he explained it to me. He advised me to flat bed it home instead of mounting the spare. I did that to the tune of $ 300 total cost of the two tows. I then spent $ 80 putting the old rims and tires I had on there.
While the tow guy was tending to my car, I texted Andre and sent him a picture of the tire and told him that I was not happy with the purchase and that as fair warning, would be posting my experience on Unilocal.Tony called me back and instead of trying to make it right or asking me if I was safe/​ok, he starts yelling at me with extreme force. Then he threatens to sue me if I post a review. I viewed that as an attempt to censor me or bully me into keeping quiet. While he is screaming at me, he invites me to return the tires and rims… I am putting that nicely. Not trusting the situation, I call them to make sure they will have the cash ready for the refund when i get there. Then, on my way up there, his mechanic Andre informs me that the tires were really not his or Lonestars, but «a friend of his». Then he says they wont honor the return at full price, they will only give me a portion of what I paid because he already paid his friend for the tires. To be clear, I bought these at the dealership and on their property, Tony never mentioned they were bad tires, Tony never claimed that they were «someone elses tires» Tony the owner took the cash from my hand, he never said they were not his tires and they mounted them for me creating a very dangerous situation per the opinion of the two guy.
I am a reasonable person. I know mistakes happen. Tony could have easiliy solved this issue by saying «I am so sorry about the problem, let me give you a full refund to make it right». Seems like a simple and fair solution given I spent $ 400 out of my pocket and hours of wasted time waiting for tow trucks and getting the tires repaired. Instead of offering that solution, he yells at me, renegs on his offer to refund the tires in full and now I am searching the internet for a place to buy new tires. I do not intend to give them my business again.
