Hello i saw a add on olx for activa 4g by person name dilip dharmani. He give his contact number.
After having chat he says he is from indian army and provide the bilke details pics, rc of bike, his adhar card.
After that he insisted me to pay 2150 for army parcel and postman will deliver it to my current location.

After making me lot of convince in name of indian army and soldiers.
I payed him 2150

After that he said it will deliver by morning. After that a guy called in name of army delivery post man and asked me to pay the remaining money before to get delivered.
After that both start convensing me to do payment. Finally he asked me to pay 6250 amount to complete the filing activity before dispatch.

He told after recieving the payment within 1 hour you will recieve the delivery then finally i paid 25% amount to him.

Then again he called me and told there is some issue and you have to pay the gst amount that is 6250 then only vehicle will get dispatched.

So total i transfered 14000 rupees to him and now he is telling i will not refund the money you do whatever you want.

Please suggest me what to do now and how to make that guy punish.

Please share me the email id or phone number where i can share all his details.
