Indian Army — indian army fraud of mobile phone selling

Address:

Hyderabad, Andhra Pradesh, 500039

Hi i am uday from hyderabad. I saw add through olx (Samsung galaxy s7 edge) and i chat with him. He saying he is in indian army introduced himself as vikram. He said i want to sell phone.
Provided his adhaar card. Asked me to send 4000 initial amount so that he will courier me the phone. I have sent him 4000 rupees through paytm. And the next day the courier boy called me sir u have to pay 5000 he said he is nearby me. Once i pay 5000 he will meet me to deliver the product. Then i asked him to come to my place then only i will transfer the remaining balance. He was refusing to meet me and asking to transfer the amount. So i realized that i was trapped. So i raised complaint in olx. And i went to near by police station to file a case against it. But the police people are not ready to take the complaint and saying its 4000 only. Leave it, we have many firs for murder cases. We don't have time for these small cases.
Sir, pls take immediate steps against him. I have all his numbers and adhaar card (Not sure how correct they are)

I am worried that i have provided my adhaar card to him and i don't know where he will use that. Please take this case as serious so that others will not suffer.
Thanks in advance.
