Query: Horrible/ Horrible Batch Recently

Okay, first I have been burning Dual Layer Verbatims for years now with only a hand-full of coasters. The last batch I orderd were COMPLETELY defective, It isn't my drive either because my other verbatims work just fine in burning!! EVERY SINGLE ONE EXCEPT FOR 3 DISCS WERE DEFECTIVE! Very upset about the waste of money, I hope I can talk to amazon about the issue. I hope it was just that batch, because wow what happened?
