Sunglass Hut/ Luxottica / Ray Ban Warranty

Good day, I purchased a pair of Ray Ban Wayferers in May 2019 from a Sunglass hut store in JHB. In July I noticed 2 spots that had developed on / inside the lens. Upon taking it back to the store it was then sent for assessment and declined warranty 3 times !!!! The supplier (Luxottica) claims that the lens was scratched. I am not sure how a scratch leads to 2 clear spots ...I am an owner of multiple ray bans that include limited edition items too. None have ever been damaged or even the least bit scratched. I am convinced this was a manufacturing issue, contrary to what the supplier claims. The customer service has been totally disappointing. I was not seeking a brand new pair but at least consideration for lens replacement. In response to my warranty claim I was given 2 options. 1- Purchase a new pair with 50% discount, 2 - Pay for lens replacement. Even though my product is well within warranty its shocking to receive this kind of service from what I once thought was a reputable manufacturer. If anyone from the manufacturer / supplier or Sunglass hut reads this - take a second to think if I would go through this much trouble to report something that you assume I damaged ? Its about principle. Saving a few company rands is clearly more important that keeping a customer happy nowadays it seems. My advice to all luxury brand fanatics - think twice before you spend your hard earned cash on a pair of ray bans that has the quality of a ****! Switch to Persol perhaps, never an issue with their manufacturing
