They broke it they can pay to fix it properly.
I cant understand why a main dealer would even suggest a repair that's not MB approved i know for a fact MBUK would love to hear about that.
You agreed with them that the bolt must be removed, and your argument with them would probably hinge on the fact that you did not expect nor where you warned that factory trained techs would be stupid enough to make such a schoolboy error.
If you give somebody permission to mount a tyre and they damage your alloy, they know that if they don't fix it you will be sending them to A&E this should be no different.
They messed up and have no excuse.
