Mason from Microsoft Windows states my Windows Certificate has been expired (its not) and I need to call him at 844-244-8133 to avoid any data corruption due to firewall breach.

Voicemail left - robotic phone message that states my Windows certificate is about to expire and I will face data corruption if not addressed. It gave me a phone number to call (not the same number on the caller ID).

Same as above- a robocall from "Mason" saying that my windows certificate is about to expire and to call another number.

same call I just received and told him to KISS_OFF   I knew it wasn't Microsoft as I was taken last March !  DONT EVER LET ANYONE ACCESS YOUR COMPUTER THAT CALLS YOU!!!!

Same as the others. Robatic call about Windows certificate about to expire.  Disreguard  11-21-17'

Same as above comments. Robotic message indicating problems with windows cert.  said to call back at 877-335-9261.

This phone number rang my phone, which then somehow rolled over to my phone provider's voice mail. I deleted the message there without listening to it.

Same voicemail as above (my phone never even rang) - a robocall from "Mason from Microsoft Windows" saying that my Windows certificate has expired, and to call 888-419-9444.

Same as above, but call came in from 1-800-1515 and the call back number was 1-888-419-9444.
