Even when you know it’s fake, the whole thing is very disconcerting. I received a scam call ostensibly from a local utility and filed an identity theft report with local police naming the utility as “victim”. The caller even told me where they (probably really) were. Police do nothing, scams continue until something breaks.

A few years back I got a call from a scammer selling a device that would help stop scam phone calls - that actually took me a while to realise it was a scam (this is like 15 years ago).
