Replying to FKS plastic heel piece fell off

Pretty bummed right now. Just went to a ski shop to ask them about this FKS black plastic heel piece that randomly fell off and makes it so my boot moves around and my forward pressure is off. It's a simple part, but apparently I have to send my bindings into rossignol for it to be replaced. Anyone else ever have this issue? not stoked right now, just mounted up my faction candies and I'm unscrewing the bindings off as we speak
