Replying to Ski's mounted wrong

So a big retailer and service company in the UK (Snow & Rock) were mounting some rossi FKS bindings I bought from them onto my brand new 181 Rossi S4s

They fucked it up, by very obviously marking them up so the bindings would be mounted backwards, mounting one ski, realising it was wrong, removing the binding, turning the ski around, filling the holes with Ptex and remounting the right way around
I'm furious. The binding isnt even sitting flat or flush on the ski, the heel piece frankly looks treacherous.
I'm going skiing on friday, what can I do

Obviously tomorrow I'm going in there first thing in the morning to get this fuck-up fixed. They have no S4's in stock, I doubt they even have any Scratch in 181. I wounldnt accept them if they did, I bought S4, I want S4. What do I say?


>>> Cliffs - Snow & Rock ruined a brand new ski by mounting backwards, filling in the holes with ptex and mounting the right way again. they didn't tell me when I picked up the skis
