Ray-BanRB4175 Clubmaster Oversized Square Sunglasses

I canceled this item like 10 minutes after purchasing it the money got taken from my account and still haven't gotten then money back ?

Hi, I saw this glasses at local Nordstrom store and wondered if the item is a genuine product as in Nordstrom ? & Do you have a polarized rb 4175 ?

Do all ray ban shades purchases come with warranty?

can i change the lenses with prescribe lenses?
