Indian Army — car purchased from army person

Address:

Hyderabad, Telangana, 500014

I murali hereby want you to inform that i wished to take a second hand car so i've seen one car add on olx.
I talked to it's owner that i'm interested in buying that car.
He agreed and the deal was done for 1, 60, 000/-
He told his name as sanjay singh.
He lives in uttarakand. He said that he works in army cannt in gd.
I asked about proof, so he sent his adhaar card photo and his i'd card proof which made me believe on him.
I was interested in this deal so i continue talking with him.
He said that i will get that car within 24 hrs. Then suddenly he called me and said that he had kept that parcel on hold. To unhold that parcel he demanded me to give 15000 rupees.
So i gave him 15000 within two instalments through my paytm account.
Then again he called me n demanded for more money.
Like this he called me and anyhow i managed to give him 15, 000 rupees. He was demanding for complete payment but i rejected and gave him almost half of the payment.
Again he was demanding for money but i said that "first to parcel the car and then i will send you rest of the amount."
Now he is neither sending my parcel nor returning my money back to me.
I just have his adhaar card photo, i'd card proof and his paytm transition number.
I just hope that you'll help me to come out of this problem. And return my money back to me because it's really a big matter for a comman person.
I'll be waiting for your reply.
Thanking you
