New 2020 Chevy Silverado truck bed has major flaws. How to make them correct it?

What is your question?

My new 2020 Chevrolet Silverado truck bed is not built correctly. It has some kind of tape or stripping on the inside of the bed. It is all around the fender and in the bottom of the bed. There are small holes in the front of the bed and 2 large holes on the bed rail. Under the rear fenders there’s no lining and there are several small holes there too. The dealership says that is the way it’s supposed to be. I’m not happy about that. How do I make them spray a bed liner on it?
