The Sharks ARE out there. Even after my first very costly experience, I found it somewhat difficult to realize in the internet age, such vicious, greedy people are never very far away, and one has to always be on your guard when it comes to talking about your savings - with anyone.
Keep the small talk short, if at all. Never offer any ‘extra’ information. Very few banking decisions need to be done “Right Now!!”. Always give yourself time to think things over or to verify any change with another branch of that bank. I’m not talking about Brokerage accounts.
I’m sorry that happened to you.
A friend’s father got bit by that but the bank locked their account and eventually credited the money back.
And the scams are so creative. The calls where you are told an iPhone has been charged to your account are currently making the rounds.
