Wife just took a call by an automated machine saying we had "misused" out internet and we'd be cut off.
Presumably if you pressed  to proceed you'd be taken through to an operator who would relieve you of some money to make the "problem" go away.
I dont know if they're targeting PN users or if its just random.
Stay aware everyone.
Fixed! Go to the fix.
Re: Scam Call
Totally random - they use auto-diallers to make many calls in succession, and some people will pick up - and hopefully put down again quickly.
I get the very odd one these days, but the displayed number is usually an obvious fake, or usually using an obscure exchange. My policy is, if I am not expecting a call, or it is an 'unknown', to let it go to voicemail - if it is important they will leave a message, if it is an auto-dialler they usually disconnect at this point.
