repair guy told me he resurfaced fly wheel without removing?
 

I hope I'm posting in the right place. I had my clutch replaced and the guy told me that he couldn't get the fly wheel off, so he resurfaced it while still attached. Can this be done? Also, it is now speaking when the clutch is engaged and it didn't do that before. What should I do or say to this guy? I think he is giving me the run around.
