I got a voicemail that was barely understandable, but it said something along the lines of this:

"Hi, we are calling from tech support of Microsoft. Your computer has been sending us error messages. Please call us back at 855{censored}"

I called the 855 number only to find that it was not in service.

I had a call from a similar person-Microsoft tech .I  received error messages. Indian English. I asked him for his telephone number. He kept dogging. I persisted. Finally I told him I got you into a prolonged conversation because you are been monitored.

It is a scam. They want access to your computer.

It's a fake microsoft number and they want to get into your computer.  They also post fake 800 number in Facebook as Click4Support and want to get into your computer.  Microsoft can only be reached by live support or e-mail.  Facebook cannot be reached by telephone.  They are hackers.

I have an HP  problem,  when i googled their support #,  this 704 # is 18554455888 toptiertechsupport.com
