Caribbean Sun Polarized Sunglasses review: faulty craftsmanship

Between my husband and I, we have purchased 3 pairs of Caribbean Sun Polarized Sunglasses since October 2016 from Walmart in Palmetto, Fl, for $68.00 each. We will never buy another pair made by this company. I purchased one pair in November 2016. Within 2-3 months the hinge screw that holds the lens in the frame fell out causing one lens to fall out of the frame. Luckily it happened at home and I found the screw and screwed it back together. In another month or two, the same thing happened, and once again, I found the screw and put them back together. The last time it happened, we were on vacation in July 2017; I leaned over to look at an item and the same lens fell out and hit the concrete. It was impossible to find the screw and the lens cracked completely down the middle. Also, I noticed that the coating on both lenses was coming off where the ear pieces fold in and touch the lens. I have today, August 10, 2017, gotten on their website to send an email about this. I really would like a refund, because they are junk sunglasses that I will never wear again. We will see if they get back with me.

The two pairs my husband had..please note I say had...were accidentally broken, but the strange thing is, the frame broke in the exact same place on both pairs.
