Hi, I feel lot of sympathy for you that such a thing happened to you, In this world everything has some negative things to it. E-Bay is nothing different. But you need not worry.
See going by what you have written I assume that you have paid using Paisapay. So even if the seller has entered shipping detail , your money is safe with e-Bay, That will be transferred to the seller only once you confirm that you have received the item.
In case you do not receive the item, you have a time limit for letting ebay know, if in that period you inform ebay that you have not received the item your money will be refunded back to you.
Meanwhile you can call paisapay team and let them know about the fraud done so that they can penalize seller. You can help fellow community members by letting everyone know
the seller's name and id also the item you bought so that they are saved from the trouble..
