Sadly, that has been the common experience for any number of us. During the course of a work move, some years ago -- with my test bench in storage and pressed for time -- I had a supposedly reputable local shop do rebuilds on three rigs, including a FFM.
All three were late -- a colossal mess, with two torn diaphragms and a perennially free-flowing FFM nowhere near its specs. After a refund of nearly four hundred dollars, which I had to shame out of them (they initially insisted upon store credit -- yeah), I haven't since purchased so much as a gear clip from them; though still receive emails for their exotic trips and, uh, tech "services" . . .
