Consumer Redressal

I had ordered 2 items from this online shopping site named \"posterduniya.com\" on 19th January, 2014. I got a confirmation mail from them immediately saying that my order has been confirmed and my bill which amounted to Rs. 1798 also got deducted from my debit card from which I had made the payment. Now its been almost 2 months and I have not received my order till now. On the 21st january,2014 I received a mail from them asking for some order details to which I replied immediately. I got a reply from them saying that my order will be shipped in the next 24 hrs which has obviously not happened. They have not even provided a single helpline number on their website on which I can contact them, only an e mail address has been provided to which I have written to them about the same with no revert. Please help me communicate this to them and to any consumer who may want to shop from this website, please DO NOT. This site need to be reported IMMEDIATELY and should definitely be shut down.
