Query: Amazing Customer Service

I ordered these sunglasses as a gift. Unfortunately, I didnt realize the different sizing on them and they were way too small. I called and spoke to a few different people and everyone could not be more accomodating. I was able to send them back for a refund and they kept me inform the whole way! I plan on going to the store and figuring out the proper size needed and then contacting CLE to make the new purchase. The glasses themselves were very nice. The packaging came with everything and glasses were shiney and clean!
