Received call. ID reflected it was a Cell Phone in NY.
Once answered there was the obvious delay in getting a live person on other end... that should always make one suspicious!
A voice with an Indian/Pakistani accent stated they were Window Support & they had identified a problem with my computer.
I told them to give me a reference number & I would call back Windows Support once I looked up the Windows phone number on the internet...
When I asked him to repeat the first letter of the Ref. number (remember he was not a native English speaker) he stated that "You are a Bad listener" and hung up.
I may be a bad listener but I am not a stupid one either
