olx mobile second hand

i want to share my personal experience of olx. I wanted to buy second hand apple device so I browsed over many platforms then I reached to olx there I found multiple people selling but theree were 2 mens selling i phone 14 and 15 both were different but they told the same story that they are in army and posted at Indira Gandhi international airport Delhi and they cannot come from camp so they will courier the phone and then after verification I can pay but the catche is they even didn't had knowledge about the thing what they were doing when I asked about army they said they were in crpf I asked video of verification from the first guy selling 15 he kept repeating trust rakho i will say if u get something like this it's red flag then that 14 selling guy i mssges him after 2 days then mssg is off and when I searched his name on true caller it showed delivery boy and location from Bihar it not over yet then one more guy had posted the similar photos like him I texted him he sent the photos and I got to know it was the same so I confronted and asked for the vc but he didn't he ran away now comes last fourth one he also told the same story I told him airport pe army nhi cisf hoti h pehle knowledge to le lo and I am from ministry don't make me fool . he also ran away then so be cautious when someone wants to sell something but saying army
