I got a call from a scammer this morning... here's a recording.
His voice is hard to make out at times... but you can hear it.

I run Ubuntu Linux on my computer - so this was always nonsense.
They recently scammed a friend of mine (who I helped, they got their credit card payment rescinded)... so when we got a call I wanted to:
i) Waste their time (if we all did this the scam would be unprofitable)
ii) Have some sport... fair game in my opinion.

*Note that I told him I was concerned this call would be a waste of time at the outset... he said this wasn't a concern for him.

My Highlights:
 - Playing the part of a clueless computer/Windws user (such fun)
 - "Calender Events in the Windows Events Log"
 - Options to "Save or Crash" my computer
 - The lack of price/cost
 - The "waste of time discussion"
 - "A is for Apple"
 - Discussion of "Glasgow/Moscow"
 - Download speeds on my broken computer
 - Discussion of warranties/contracts and Dell
 - 

See BBC report - including Rory Cellan-Jones' recording when they called him.
