I've never had to deal with a possible "quality of service" issue with CGC, but for what you probably paid to get it graded, slabbed and being one of the top demanding comic books, I'd be calling them to see if they are willing to do something about it. Maybe re-slab it for free. Not sure if pressing would be a good idea. Books in too bad of shape can actually take a hit from pressing. I had a Hulk 181 that was a 6.5 that I had pressed and re-graded. During pressing, the cover detached at one of the staples and it came back as a 4.5. I didn't use CSS for that press job, but not sure if the result would have been any different if I did. To be fair to the guy who did press it, he did warn me before hand that it wasn't a good pressing candidate and it was my call.
