Indian Army — offering activa and cheating

I saw a post of activa on olx by some indian army person stating that he has to shift and so he wants to sell his activa. My mom made an inquiry and that person told yes he wants to sell the same for 27000 only 1500 kms run and bought in 2019. Now we spoke with him on phone and it seems to be genuine. Today we decided to purchase that activa he told give us the token amount so that i can make parcel transportation. We gave him 2000 rs and after some time he is asking give me 5000 so that i need to show for transfer.

I will urge indian government and indian army to take strict steps of the fraud happening and people who wants to buy a 2nd hand activa. We got saved because we did not pay him completely.
