got scammed *HELP*

we're from thane, and my roomate got scammed when he tried to book gas connection+ stove for our flat. he got this number for gas connection through online (which we were not aware bout that he got this through online and not in-person). so they said through text and call, and asked us to send rental agreement, house address, and sent a QR to send ₹3,200 for both gas connection + stove, to initiate the process within the day. after my friend paid him, they said that the money has been sent to a wrong account, so asked send to send ₹3,200 + ₹3,000, (saying that the 3,200 was only for gas, not stove). when we said that we don't have much money right now, they said that then send howmuch ever money we can right now, and said that he'll refund that 3,200 within 2 months. this sounded suspicious. this is when we came to know that our roomate got this number through online. so we asked the guy to send us their office address, but he keep on saying "first you send the money, then I'll send address". so we tried calling the number, to which we paid the 3,200, asking to resend the money. he keep on saying "bro i'm busy right now, call me after 10 mins". after some time, he blocked one of my roommates who called him. then I tried calling, and he keep on saying the same thing. my roommates wanna give up on this, but I don't wanna give up that easy. i'm ready to go any extend to get back that ₹3,200, but someone guide me how to. it's not just bout that money you know.. i just hate to see how inhumane these scammers are, to steal easy from people who are struggling to earn and live. https :// posts .gle /5EMgwUMLCxCGvgwKA just remove the spaces in the link, sorry i don't whether it is possible to attach that fake online location he got.
