Bewerly.com — dress ordered but not delivered

Dear sir/ mam,
Recently, i ordered a dress online through this website (www.bewerly.com).
I got to know about this website through facebook as i saw an ad while browsing the same,
I made the payment using my debit card as cod is not available.
My order was supposed to be delivered but i have neither received the order nor able to contact them.
Also, there website no longer exist now.
I have now seen many complaints filed against this very company on your forum.
I wonder why platforms like facebook, etc. Don't discourage such advertisements/ act. They should do proper background check of the companies/ person.

Would request you to help me with this case as it is cyber fraud.
