Yesterday I put an add up for a sofa on gumtree. I had someone message very interested saying they wanted it and could I remove the add. I said to please pay via PayPal or bank transfer and sent him my email but not my bank details. I then got an email from him saying he was in a wheelchair and having an issue with his courier they wanted paid first, so he had sent me £500 and bank details of the “courier” and could I please pay this and then PayPal would release the funds to me. This is when alarm bells rang. I then got a very fake looking email from his address claiming to be PayPal threatening legal action and a link to pay, and if I didn’t pay in two hours they would suspend my account. I emailed him back saying this is obviously a scam and please don’t contact me again. He said what do mean etc PayPal took the money and it’s non reversible and did I not read the email from PayPal ! I said the email was not from PayPal it was from you. I didn’t click any links but I’m just panicking a bit because he does have my email address and address and phone number now so I’m worried he can get access to my email account somehow as these scammers know every trick in the book. What action should I take from here ?
