[Resolved]  Printvilla — mobile back cover

I have order a cover 4 days ago.
And the company is not responding.
And from two day whenever i go to the site printvilla.in
It say "under maintenance"
I have also paid the amount via paytm.
Now what to do!? Please take strict action against it. Please try to catch this type of companies so that they can't fraud anyone in future.
It would be grateful if i get my money back.
Thank you
