Agree with QCKTVR. Why were they removing the harmonic balancer on the crank if the head gasket is bad? That seems like replacing tires when you wash your car! Head gasket replacement is generally fairly straight forward. Many times it can be accomplished with the engine intact, though I'm not sure with this particular model. As long as dirt is not introduced into the mating surfaces and head bolts are replaced and torqed in the correct order, it should have been a no brainer.
It really does sound like they may have twisted right when they may have needed to go left though. Though at this point I don't know how one would determine fault.
That bolt, like all critical bolts on the engine, is not just torqued but stretched to a specific elastic range which makes them somewhat hard to break loose. So yes, an impact tool is best to remove them vs a breaker bar.
My vote is the shop is at fault on more than one level here.

YOU HAVE TO REMOVE THE FRONT TIMING COVER TO REMOVE PRIMARY AND SECONDARY CHAINS AND THEN HEADS. THEREFOR THE BALANCER DOES HAVE TO COME OFF. ALTHOUGH IM SURE SOMEONE WILL SAY THAT YOU KNOW IF YOU USE TIE STRAPS, SCOTCH TAPE YOU CAN REMOVE THE HEADS WITHOUT PULLING THE TIMING COVER......
