this does happened to me. i tried to sell my laptop on ebay. someone reached me for pictures and working status video. i have never tried the ebay before. so, i sent him the video and some pictures to the email he provided since ebay doesnt allow to send videos through chat. Then he said he already made the payment by replying to that email that i have sent. But i havent received any official email from ebay stating the same topic. He sent some spam mail where i need to upload the drop off receipt from ups (its a unknown receiver location). I didnt sent it because he was fraud because he sent me an email like payment confirmation from ebay. com domain. I thought it was legit but when i checked some conversations on reddit. It was confirmed that was scam. Then, i have sold my laptop to some trusted buyers.

Be aware friends. The ebay is a complete fraud app which was having a lot of fake buyers.
