Got a scam call yesterday morning. An American-ish accent, but quite rusty, I suspected they were using an AI voice changer.
They said "Am I speaking to <my full name>?". I did not answer that and instead asked what company they were calling from, then they immediately hung up.
I guess people who ask that initial question are disqualified for their scam, they're looking for more gullible folks.
I simply don't answer calls from unknown numbers. I feel like it's my right as a grown-up.
