That's just a damn shame.... will the blaster reimburse you for the damaged parts? .... he should. In fact, he better...or pursue legal options..
Since those parts can be replaced, maybe you can still save the car. That's the car you got from Chris, correct?
Did the blaster use baking soda or sand for the blasting? I've done sand blasting myself and have ruined a hood (lesson learned), and slightly warped some fenders which were easily repaired.
