Timtara.com — Cheating worth Rs 31000 laptop

Address:

North 24 Parganas, West Bengal

I bought a samsung laptop worth 31000 after paying online to timtara, order#1021 7528. It was 17 days back. However, neither they have given me the product nor refund the money. Their customer care is not reachable over phone. And they are also not replying my email.
In a nutshell, they have my Rs 31000 and also the laptop I bought.
I'm all prepared to take action against this.plz suggest me if anyone knows about the best possible action that should be taken against online shopping fraud. My contact details are mentioned below.

Thanks
Subhankar
