I had one today (mobile phone), the first I've ever experienced not on a landline.
Phone rings. UK landline number (supposedly).
Hello?
Pause for a few seconds (presumably the time taken for the automated system to register that I've answered and connect an operative).
Hello?
Hello.
I'm calling from xxx insurance about your car crash recently (I can't remember the name they used, but it sounded legitimate).
Ummmm... (short pause) What crash?
The recent one you had.
I haven't had a car crash recently ((nor ever!); especially as I haven't driven a car since late September!)
Oh... what about any of your family members or friends?
Er... nope
Any medical negligence, accidents at work or anything?
Nope
Ok, bye.
Call ends.
It took me a bit of time to actually realise it was some sort of dodgy call (although it wasn't necessarily a scam, probably more of a cold call), at first I thought they must hav the wrong number. The woman on the line had no accent I could detect, and sounded normal.
