got ripped off on trans rebuild

and on top of that,when i went to pick it up,it took off across the lot in nuetral,when i hit the starter,good thing no one was standing in front of me.so much for the nss,and the linkage adjustment,left it there.he called and said all is good, went to get it ,same thing,wtf?he said you have to really push hard on the neutral button,didnt have to before.driving it home it goes from second to third way to fast,almost immiatly(sp).should have taken it to a&a transmission in indianapolis.
