So I was selling on eBay when a buyer reached out to me and offered $700 for my laptop. Even though the laptop was only $550 but the buyer said the extra money was for shipping and handling. Then they said to send a PayPal request and I did. Then I got a fake email from eBay saying to send out the laptop so I did. Then I didn't receive the money and the fake eBay email said to send $700 of gift card but I didn't because well that was a lot of money. Then I confronted the buyer to be a scammer and they didn't disagree and I asked for them to send my laptop back but they said they did even though they didn't. I don't know what to do know.
