Deepak Sharma Kutani Vimlawati Devi - Fraud payment transaction Cyber crime

So, today I got into a fraudulent transaction with someone named Deepak Sharma (I don't know whether the name is also correct or not as the name is different on different mediums) but the number is **********. So they contacted me through OLX on one of my ads and then got me into a conversion saying they can transfer the money through paytm only. He was helping me out through the whole process of linking my bank account and then sent me a QR Code to scan and told in paytm you *st have to pay and then you receive the amount. I did for * rupee and * got debited and then * rupees got credited then he shared *,*** rupees scan and pressurized me to pay before the QR expires i did and till the time i was checking for it in my bank account, In pressure i did it again for *,*** & **** and **** to get the previous one back. In total i did for **k. I know it was my stupidity to trust someone like this but this is a harassment in my opinion, literally fucking up someone mentally and then when my father and friends contacted him he said "You just got into a fraud, haha". What kind of humanity is this. I hope to hear from you all soon on this as you all are my last hope. Hope you could help me.
