AA Rebuilt inc. / improper engine overhaul

I ordered 2 remanufactured 500 cadillac engines $4935.00 in April of 2008. They sent older models than I ordered, they where not fully assembled, missing parts and some of the parts they did use where unserviceable or partially cleaned. I tried to call them, no response yet. The company who actually did the remanufacture? was Blaines Motor Supply Co. in Dallas Tx. I called them [protected] and received a bunch of BS about the problems I'm experiencing. I've been a licensed mechanic for 25 yrs. and order 4 of these engines per year. I've never even seen an overhaul this bad and to call it a remanufacture is a joke.
