I think you need a drink
My RJT's front fascia is a slightly different color, but not super noticeable. Also received my car in late April and I am an R6P with a vin <1000
You can also take your car to another chevy dealer in your area if you are not satisfied with your current one (sounds like they are jerking you around). This is what I do. The dealer I purchased from is a good 30 min away, so I have taken mine to the one that is 7 min away when things needed to be fixed.
