Shop dented my rear wheel while mounting new tires

As the title says, I got some Diablo Rosso III's mounted at a local motorcycle shop and while I was installing them I noticed a pretty sizeable dent in the rear wheel. Normally I'm not one to make a scene about this sort of stuff, but I'm pretty peeved about this one. Has anyone else had this happen to them? What was the resolution? At a minimum, I'm going to call them back and tell them what happened.Photo 1: http://imgur.com/gallery/G4cOP0MPhoto 2: http://imgur.com/gallery/HIei12l via /r/motorcycles https://www.reddit.com/r/motorcycles/comments/9za2ll/shop_dented_my_rear_wheel_while_mounting_new_tires/?utm_source=ifttt
