The Better Business Bureau is warning people about a new scam involving payment apps like Venmo or Zelle. The trick involves the scammer “accidentally” sending you money, followed by a message that says “Oops, so sorry. I didn’t mean to send you that. Can you please send it back to me?” The BBB says it’s a trick – the ‘accidental’ money comes from a credit card that gets canceled – invalidating the payment and removing the cash from your account a few days later. But by then, any money you sent them is long gone.
