Got calls 4 months now saying windows security centre gotta be a scam cause it costs $80 dollars apparently

Any one know this number they say they are from PC Help and Support.  They ring my house every day wanting me to turn on my computer.  They are very pushey and often Indian accent which I can never understand.

Got two calls from this number today. First call I asked for a street address so I could bring in my computer (I'm not sucked in by this scam), mysteriously the line went dead (hung up on their end). The second call came 15 seconds later. I managed to find out that its from a call centre in Brisbane Queensland, the operator identified himself as 'Alex' and that he was calling from microsoft. I asked him who he worked for because microsoft doesn't have a call centre in australia and he said a company called 'PC Help & Support'. No street address divulged unfortunately.

I was phoned today at 2.30pm by this number-a woman with a strong Indian accent.  Spiel was that she was from Microsoft Computer Technical Operations Centre, and that my computer was about to crash.  She asked me to turn on my computer and follow her instructions. [My computer was on already-I just hung up]

If you ring the number back a recorded message says they are the Microsoft Service Centre.

Got a call from this number claiming to be Windows Computer Maintenance.They said that my anti-virus program has malfunctioned and that I should follow their instructions to fix the problem. Very rude Indian sounding lady called Annie DeCosta. Can anyone confirm if they are legitimate or not? My feeling is that its a scam.

Got a call from a rude Indian lady "Nancy".  Says the company is PCHelp & Support.
Trying to lead me thru the windows event viewer scam.
