Gutting! It’s a real shame you didn’t take before pics and get them to have a pre fitting walk round with you noting no damage. It’ll need a proper diamond cut refurb, using the decdicated lathe.
This is exactly why I now take mine to a wheel refurber to fit tyres (Lepsons). Got sick of careless tyre fitters wrecking wheels, often prying off wheel weights with god knows what, That way if they bugger the wheels up they can refurb them! But they do a perfect job.
