They don't support B&L Ray Bans warranty-wise since it's under Luxottica now. You're best bet for finding another pair of lens for the predator 1 is on eBay or you could even find a new old stock pair on ebay for around 40-80 dollars nowadays, they are quite inexpensive.
I made a mistake but that's certainly unsettling, Italy must be getting hit hard by the economic crisis. If I were to buy modern Ray Bans I would still stay away from the China made models even if they claim they are "authentic". China is the counterfitting capital of the world. How are you supposed to distinguish from an authentic Chinese pair from a well made Chinese fake now?
