@Edent The scammiest such call I ever got, I asked for their name and extension.
Then I hung up and called the number on the back of my card.
It was legit.
Like for real, I've had legit calls that sound scammier than any scammer; so I assume they're ALL scams now.
I don't trust them unless I'm the one that initiated the call.
If the call comes in to me: I give zero information, I confirm zero information. I get enough information from THEM, then hang up and call in to confirm.
(And yes, I've had an absolutely convincing call that thankfully I was already on my "treat all as scams" or else I would have absolutely believed it and given them info.)
