Replying to Binding ripped out of ski after 2days

Hey!

I got some pivot 14 duals mounted on brand new chams 117 at a shop "professionally" last week.

After skiing them for 2 days without a lot of action, one heelpiece ripped out of the ski, fortunatly it didnt hit anyone when it went down the hill.

what should i ask the shop which mounted them (without glue) for?

a remount only doesnt sound good to me, as the ski is a lot less worth now to me.

Thank you!!!
