ok, believe it or not I personally have made this mistake before. sometimes when we press save on the computer system, we run off and assume it worked, when in actuality it didnt.
my dealership uses the same computer system, and I constantly have to double check my vins when i sell a car
so OP, i doubt they were trying to screw you, knowing that you would (obviously) notice it was the wrong color when you took delivery. Surveys are too important for something that obvious
