OLX.in - Fraudster user on olx.in

Dear Team,
On **nd November **** I posted an ad on olx.in for Samsung Galaxy note *. Ad Id **********. As soon as I submitted this ad, I received messages from * olx users they both offered price more than I listed.
Fred James claimed to be from Canada and asked me if I can ship the item to Delhi since his son's birthday is near.
Another guy named Terry James claimed to be from US Military and asked me if I can ship the product to Deira Dubai.
They both asked my account details which I shared and I received the confirmation mail well drafted that the amount is deducted from their account and will be cleared to my account as soon as I scan and attach the shipment receipt with the emails I received.
I was suspicious as one email I received was with gmail.com and another was with usa.com
Bank never use domain like Gmail and USA.
And upon searching on Google, I got to know about this kind of scam. I request this forum to inform olx.in to catch such fraudsters who are trapping innocent users.
