Poor quality and bad customer service.

I returneed my glasses after I noticed the anti-glare coating was coming off. Waited more the a week for feedback. Everyday I had to flow up. Customer service is pathetic as well as the quality is a understatement. Had glasses made last year. In less than a year the anti glare coating came off. I hardly wear glasses cause, I wear contact lenses in between. I've been wearing glasses for years and first time I experienced something like this. They refused to repair the lenses. According to them it is not a manufacturing deflect. How does coating on lenses and come off in a year???
