Answering unknown number calls on my cell phone like a receptionist really confuses scammers.

"Good afternoon, thanks for calling!"

"Hello."

"Hi, who's calling please?"

"This is Experian Security Services calling to discuss an urgent issue with your account."

"Who are you trying to reach?"

"I am looking to talk to the owner of this phone number."

"I'm sorry, I'll need a name to help you."

30 seconds of silence.

Call hangs up.

Excellent!

The last time I had a 'your computer has a virus' call, it was quite easy to drop into 'Busy ops department':

scam: 'yr computer, etc'

JHR, tired: 'right. which one?'

S: 'its running windows'

JHR: 'do you have a service tag?'

S: ' ... '

@JuliaRez @vees I distinctly remember frantically searching for windows XP screenshots from Ubuntu to play along with that sort of scam, whilst acting as a half dead old man who needed everything repeating about 3 times and couldn't find his glasses for a few minutes.
