Ok so the other day I was on twitter and saw this post of $18 Ray Ban glasses On sale. So I clicked it and I obviously had to buy some because Ray Bans are expensive. So I bought them and rousthee curved them two days ago and when I oped the package it didn't have no order form or receipt. I started thinking and getting suspicious about it. When I took them out if the case they were not the ones I ordered. They are very very light on weight. They looked completely fake right away. So I searche up how to tell if your ray bans are fake. And it showed me and I examined them and its true  some of the parts aren't even on the aviators as the ones that are real. Yesterday I sent them an email and no response. Today in the morning I sent them an email but nothing. I'm pretty scared because I wasted a lot if money on that stupid package. And I want my money back but they just won't respond.
