Printvilla.in — booked a mobile case cover

Website:

Printvilla.in

I have ordered the mobile back cover for xiaomi phone. The money 194 rs got deducted from my paytm account and i got the order no. 94162. But now when i am opening the site it is showing maintenance mode and have not received the product also.
It is like more then 15 days. Only this was the message i received on my gmail and by then there is no communication from their side. When i check it online the site is in maintainence mode and no order update no shipping update from the company side.
It is a complete fraud case and fraud company.
I want my refund back and get this company shut down so that they can't do fraud with the innocent people.
