Not uncommon. I've had this happen with alignments, too. Ruined a set of tires when a dealer claimed to have done an alignment but didn't. Now I always request a printout after doing an alignment, and I will often take it to a second place to get it checked.
I like to hide the wheel lock keys so that they will have to call me to find out where they are in order to do a tire rotation. If they don't call me, I know they haven't done the rotation. Or they were resourceful and found the keys - in which case, I will usually find them in a new location - on the seat or in the glovebox or something.
