With a 2 day old liner I'd have them come out and fix them!!! Even if it is 'ground water' when they come to drain the pool down and fix the wrinkles, they can show you that it is water under the liner causing the problem (and then you can decide how to deal with it)

DO NOT let them off the hook - your new liner shouldn't have wrinkles on the floor, for ANY reason!!
