Texas used engines J&S Sold me two junk engines magnolia Texas

Bought a 5.3 chevy engine $1000.00 took me about a month to get it installed, i do my own mechanic work, partially my fault I Didnt check oil pressure because after everything was hooked up there was no oil pressure, so he said take it out and he actually picks it up from my house and drops off another one. This one i later found out had 3 broken exhaust bokts in the aluminium head. So he say take him the motor to cube smart and they'll fix it or swap the head, i said no way man, you come fix it! So he said just bring the head and ill  swap it. Ok I'll  do that. Then i had to spend another $100 on new bolts because their non reusable and head gasket. He doesnt answer calls or texts. If he does its rare, and he tells you " oh ive been busy" .   Yeah well I'm a customer!! Then he said he didnt even have to help me at all with the head and that i voided the warranty by taking it off, well excuse me Jason but you told me to take it off!!! Now its finally running and sound like a light knock in the motor, ....im a tell you what he does! When you call about a motor, he hunts one down for half the price he tells you and gets it out of some other junkyard hoping its goodnor i really think he doesn't care because he already has tour money, i probably spent $1500 on this motor, and i just dont have a good feeling about it! I hope he wnds up in court and has to pay everyone back he's screwed! Do not deal with this company!! He's  a liar and has one mechanic in a storage lot,his shop has junk laying everywhere, he just plays this big shot, his website is nothing like what he represents!
