Indian Army — I came a/c a bike deal on olx.

Address:

Chamarajpuram mysore, Mysore, Karnataka, 570005

I came across a bike (Royal enfield) deal on olx. Owner his name is vikas patil who is working in kempegowda airport bengaluru, wanted to sell his bike at a meagre price of 40k. When asked about the reason he told he's gonna shift to mumbai as his job was transferred so he wanted to sell it & move on. Initially he asked me to pay 3150rs for parcel of bike. To which i agreed & a bill was given.
Upon parcel reaching my place the truck driver supposed to parcel called me up & asked me to pay 11.3k since it was a speed delivery. I paid him the money. After crediting he called me & told that the indian army would be billing amount above 10k so split the amount & send, also he stated that 11.3k (Not billed) would be refunded by cash. I did as he told me. Later after crediting he again called me & said since the parcel to be received is being received late the bill would be generated only if the rest amount is paid. Upon a lot of conversation i agreed to him, paid him full amount. He later called again telling me that the insurance of the bike is expired so to renew it pay 12.6k (Also stated that even this amount would be given by cash by the driver). To which i disagreed & asked him to repay my amount.
Now there is no response from his side for this!!.
He gave me

Now he's neither picking the call nor is there any response from him.
I later came to know that there is no such indian army parcel service available...
