problems with repair shop

[retodd7711]

I need some advice. The first week of April I took my 69 to a repair shop for some work. New clutch and u-joints. Diagnose shifting problems, and install floor pans and rocker panels.
After two weeks of no action I got impatient and talked to owner. The next day they removed tranny,cut off rocker panels.
after two weeks of no action and promises to start tomorrow finish Friday.I pitched a ***** fit. I demanded a schedule and was told it would be done Friday.
As of today it has been 6 1/2 weeks and the put the floor pans in the truck and tacked the edges. I was just there Wed. night and was told Friday would be finished.Today is Friday and my truck still sits.
I have no idea what to do the truck is not driveable or It would be gone.
I don't really know how to reinstall a tranny and if I take the truck there is no guarantee I would gt all my parts back.
I just want my truck back and I can't get dude to finish it. This is a liscensed shop not "some guy's garage.
Please tell me where to go from here
