My mum very nearly got scammed, it was one of those phone calls pretending to be BT about the phone line getting hacked. It was only a few days after my dad died, and she was in shock and not thinking straight, and panicked because she was waiting for the coroner to email her and went into stress mode at the thought of not getting the email. They got her to install an app on her tablet, but when they asked her for bank details she refused. They then spent nearly an hour trying to convince her, getting her into a worse and worse state. I've never wanted to kill someone as much as I did when I found out. Particularly when I found out that she'd told them her husband had just died and he'd always dealt with computer stuff... I knew as soon as they heard that they just went "ker-ching we've got a juicy one". Still makes my blood boil two years later.
