Damaged and low quality, small in size products

Hi I ordered 3 shirts from this portal on 12/10/2014 amounted rs 900. I received these products 3 days back. Product quality of these products is extremely low.. and it was not even 10% of what they have shown in their portal.. they have shown very good quality shirts which is very bright in colors too, but what I have received is completely shit.. also products is not as per the size chart, it is small too.. means no one can wear it any how.I marked them complain about it same day I received the products, I got a reply from them that we have checked quality before sending so cannnot change it.. I replied that products are too small and dnt even look like what u habe shown.. quality is very poor too.. they didn’t reply.. I am following them again and gain but no reply yet have been recieved.. they have no t provided any contact no also, so that no one can contact them. They are making fool of public by lucrative offers on their portal and then dnt even get contacted.. I want my money back and want to teach these people lesson. Kindly help.
