Olx India — nikon d850

Address:	410209
Website:	OLX

About three months ago i bought a nikon d850 dslr, as it was a very expensive camera (2.43 lakh), i coudn't pay the emi on time so i decided to sell it on olx so i posted the add on 11th june and people started asking about the features, warranty and price, but later on a guy name billy hart asked me if it's available and he agreed to pay 2.15 lakh for the camera and asked me to ship it for her sister who is in u. S. A through dhl courier service, first he asked my bank details and i gave him that through whatsapp and then after a while i recieved a mail from penfed credit union bank stating that i have to complete the shipment and have to send the reciept of the shipment as a proof and then they will transfer the amount into my bank account within 2 to 24 hours, as the shipment completed and i gave them the reciept they asked me to wait until the shipment status changes to 'dispatched' then they will transfer the amount 226'000 (2.16 lakh + 10'000 courier charges) as the shipment status changed i recieved another mail stating that i have to pay 15100 inr due to the financial policy i have to pay the amount to the security and exchange board of india (Sebi) thenafter that instantly they will transfer the amount, i asked mr. Billy for help and after a lot of discussion he asked me to pay 10100/- inr and the rest 5000/- will be payed by him, so i asked my friends for help and i paid the amount, i mailed them the transaction id as well as the reciept of the transaction, after few hours i got another mail stating that i have to pay 40'000 inr because when they contacted my bank for routing transit number to complete the transaction but my bank couldn't provide that so instead of that they gave swift code which is used for international transactions, so either i have to pay 40'000 inr or otherwise they won't complete the transaction,

Later on i discovered that soon they will have my camera as it was already dispatched from india to usa and they have that money i sent.

Please help me with this.
