how i avoided scam

on 29 June I posted an add on olx for cycle .someone randomly called me to buy it. Deal was done on phone . I told him to come at home to see the cycle and then decide to buy.He told me that first I will pay you money online then my worker will come and take the cycle. then I gave him gpay detail.he called me that I will not pay from g pay I had an another app through which I will pay the money and money will be recieved by tomorrow. he pleased me to follow some steps so u could receive money. i told him to pay cash but he has diffrent reasons .now i was surely know that he was some fraud ,coz no one would send money first im.his name what he was saying was RAjesh Kumar and on true caller Adil. I totally blocked him then.his phone num is [PHONE]
