Exhaust manifold service

My experience here was HORRIBLE! My truck went in for an exhaust rattle noise, was diagnosed with a broken exhaust manifold bolt in the head. Cost almost $800. When I picked the vehicle up it had the same rattle as before, and when we crawled under it we saw that one of the bolts was still broke off!!! There were no new bolts on the manifold, they claimed they "reused the old ones". Bolts are cheap, if they took them off why not replace with new ones??? My opinion of this place is to STAY AWAY FROM HERE. They did not stand behind their work. To me, this place is a SCAM!!
