Absolutely Disgusting Service

I purchased your High Definition Sunglasses in June, you get 2 pair in the box, a black and a tortoise shell. Within a few hours, the black pair broke at the magnet on the arm. I returned them to Checkers and they replaced them, but never gave me a new receipt. Guess what!! The black ones have barely been worn and they have broken int he exact same place, obviously a design flaw. I have tried to email you, phone you and even sent messages to your Facebook page. I am hoping this will get some response, they come with a 12 month warranty, maybe it should be longer, but what is going to be done about this. I want an answer!
