Can my account be hacked like this?
Someone sent me $15 dollars unintentionally, and then another person requested $20 for their money back. I didn't respond to that cause it wasn't the same person who sent it. Now, the person who sent it is requesting the $15 back. If I refund it, is my bank account at risk? I'm not really familiar with cash app like that. I don't know either of these people.
