I ordered 3 pair of glasses. I could not see through one so I sent back for exchange. The glasses were out of stock and I could never get response from them on refund amount. The glasses came back in stock and they keep asking for a segment height that I can't measure because I don't have the frames. They always say they've emailed Refund Dept to get me off chat or phone. Their customer service is horrible with stock answers to get rid of you. Do not buy from here!
Update: It's only gotten worse. I was told yesterday that my replacements were in the 'final stages of production'. Today I get email that the frames aren't available and to pick a new pair. So we're starting over. This has been the worst and most frustrating customer service experiences for me. I used to work in claims so I know when things go wrong. This is horrible. It's not worth your time. We're at 7 weeks since I sent exchange back.
