Query: DVD's don't work and there's no replacement

I have to say I'm really disappointed. We've only looked two of the years so far, and already 2 of the 8 disks don't work. You can actually see where the coating on the DVD wasn't applied evenly so it's no wonder the DVD won't play. I've tried the faulty DVD's in several different players, including 2 different Blu-Ray, and they just "chug".Unfortunately, short of returning the entire collection, there's no recourse. There's no way to talk to real human at Amazon, and even if I did, Amazon can't get replacement for just the faulty ones. There's no information on the manufacturer or a way to contact them. So we're SOL.Very, very disappointing. Not up to JK's quality standards.
