Pretty odd, I think Last month he contacted me on localbitcoins to buy some btc.

Wut is RBI? Brah

Localbitcoins is a p2p trading platform, they don't take any Fiat nor give any Fiat.
Buysellbitco.in is a different case, it's Mahin's personal buying/selling site

Well I doubt there's any other way except signing a message from that address

He can sign a message (Order number) from his address (from which payment was sent) and provide you address, signature and message.  You can then use Blockchain.info's api to verify that message.

You just said this.

edit: Sorry I am not able to understand you. You want to sign a message from some wallet or what?

or are you talking about this kind of messages in transactions.

Which wallet you are using?

Bitcoins are available in stock.

Just completed one more escrow. PM me if anyone needs escrow service.

All I can say is "lol".  Anyways Goodluck mate
