Kaunsa.com — product has not been delivered yet

Kolkata, West Bengal

I have purchased a Rayban sunglass on 18th Jan 14 worth INR 699. The product has not been delivered yet, nor have they provided me the shipping details of the product. I am continuously calling their consumer care executives but Customer care persons are always bluffing and they are not in a position to answer if my order will be delivered. When I ask for refund they ask me to raise complaint ticket online. My complaint tickets are answered with an automated reply without any specific resolutions.
Whenever I call they say dispatched and will be delivered by 2 days and this story is happening for almost a month. Now I understand they have no idea of my order at all. As per my experience they are a group of frauds. Never ever believe them. Now they have stopped receiving calls in their help line number.
I would request to take serious action on this matter.
