Replying to Skis broke first day out, Who is to blame?

My friend recently bought some 2019 faction candide 3.0's from Evo. He went to Sports Den in SLC and mounted them with a pair of old look pivots. Yesterday was his first day using them and towards the end of the day we noticed the problem in the attached image. My question is, how should we go about getting refunded. Should we try and get the shop to help us get this resolved or should we just speak to Faction or Evo directly?
