What to do when there is a fraudulent business on facebook?

HI I have ordered some sareers from one person.I have seen posts in facebook group of Banglore wholesale market.There "Mahek Saree" named some one posted many pictures of sarees and gave one whtsapp number also to contact them to buy those sarees. I liked those sarees and pingd them.they took my order and address and told that also the courier will be sent to you next 2/3 days.I ordered on 9th September 2017.They told me to pay via paytm/transfer the amount to their bank account.I choosed paytm option and i transferred 1070 rs to 915779981(Manoj).My wallet txn Id-14378608454 and i added comment there also "Amount for two booked saree".Afterwards i am calling them to know the status of my shipment and whtsapped them but they are not giving me any replies.I have posted this to facebook also then i came know already many peoples are cheated this but the thing is no one did any report to police or facebook,Is this thing is not stopped then many others will also be cheated and this process
