Olx fraud - OLX fraud victim

I posted adds of two maxi for which I got call from buyer saying u first pay me *rs for which I agreed. He said only then if u send I can give u back money. So when he asked me to pay *rs * times I did n he asked me to pay *,***. I did as he said u give request in Google pay. He asked me if u click proceed u will get the amount. After he received this *,*** he asked me to pay again either *,*** or *,***. I became alert n asked me to refund the payment I did or give my money back. When I asked him go wait let me check he dint even give me time he said I will wait in line u do fast. I lost my * ***. When I asked him to give his identity details he dint give. He gave invalid someone else aadhar card without address. The name he said n the name mentioned in aadhar card was different. This is how I was fooled from old fraud. Later on I received messages saying don't scan QR code. If I would have got these messages earlier I wouldn't have been an victim.
