repair of a turbo

My Veggie school bus/RV broke down and I took it here with a blown turbo. They had us on the road quick enough, we made it 3 exits away before it blew again. 3rd time we made it 50 miles. We continued our trip in the car and left the bus. Took these guys over 3 years to fix the turbo problem. When I flew down to pick it up I found they Stole the $1500 sound system out of it. Marty is the only one with the key but it was locked when we got there. He says it was probably someone that used to work there but they wouldn't do anything to compensate me. Got it started and it blew smoke like mad. wouldn't stop. He didn't fix anything. I took it to the nearest Diesel shop and they told me the turbo was band and now it had a blown head gasket and I'd never make it back to Seattle. I said screw it and tried anyway. We made it but it was never fixed. over 3 years, a lost sound system, and over $2000 and this was one of the worst mechanical experiences I've been through. BTW I'm a mechanic and I own my own shop. I'd never do this to a customer. Everytime I called to get status it was some lame excuse or another. Steer clear of this place, they're horrible.
