I'd be pretty annoyed if that had happened to me. Ask for a set of Reserve stickers to put on the bat, it's just not right to have stickers 2 grades below the actual bat. (Unless specifically requested)
The bats themselves look pretty decent, although hard to say as the lighting bleaches out the grains a little bit. The performance is the key, I have found that my Reserves have outperformed my Private Bin and Special Reserve bats. They sound a little bit 'clunky' upon contact, but the ball absolutely rockets off them. Quite a unique pressing, haven't quite come across any other bat that's quite like Laver!
Hope you get it all sorted out, I would trust James, as I've dealt with him a fair bit in the past. Just keep an eye on the weight, as it's almost certain to increase by an ounce over time!
