Guess — Google's complain

I filed a complain against googles which i purchased from Guess shop in United states. Despite of that complaint it has not been addressed properly. One of the person contacted me from guess but still the issue is unresolved. Now nobody is responding from their side anymore. The complaint is regarding the googles which broke due to the heat. They broke when i kept them in my car in India. I sent the pictures as well and that problem seens to be the issue with the profuct that was used in the side of the googles. I can provide the product too and the receipt as well. This is very didappointing when you buy a branded product and the wuality is inferior. Please contact me asap and help.
