This is really messed up. I'm honestly shocked.
As far as CGC's response, my first question will be how can you 100% prove it was the same book. On such an EPIC screw up, I think they may go to the denial defense. Not the same book, never happened, etc. I really feel for you, for "everyone" to look at it and swear it was trimmed and now it's magically not,
I'm dying to know their response. I'm trying to imagine a scenario where you will be happy by the outcome, and I'm not seeing one. Sorry brother, godspeed!
