Need help, got taken advantage of

Hi, my name is Isaiah, and I'm raising money to avoid being homeless, I bought a car from a "trusted" performance shop two months back, and the breaks went out on the highway which caused me to crash, when I towed it back they just offered me a different car, that car clutch/drive train blew out on the highway not even 24 hours later. luckily I didn't get hurt to hurt anyone, after that, I was then coaxed (at the time I didn't know it) into buying another car from them, and since then, I been waiting for a car, and when I asked for my money back, instead of $3200 I only got a check worth $637 and assaulted physically and surprise that check bounced. I tried to get law enforcement involved but sadly, there was nothing that could have been done legally.  so now I'm in a hole and nearly homeless, currently trying to sell everything I own. I have rent due by the 12th of October, but I'm so thankful for anything people are willing to give.
