I agree! Call or email immediately. Mine weren't nearly that bad, though my Phal. equestris already had the beginnings of root rot, and the violacea x bellina had snow mold in the media as well as the same dark spots yours has on the bottom leaf. I've been keeping a close eye on that leaf and it doesn't appear to be anything more than cosmetic. At first I thought it was scale!
At any rate, they need to replace or refund the Iwan. (I think if it were me I'd ask for the refund) I know I won't be ordering from them again.
Oh yes, and repot all of them immediately!
