SPAMMER!!!
I rejected the call and a voicemail was left saying, "Microsoft has stopped all the services on your computer. To get results, call 1-855-539-4926..." Which is BS because I don't even own a personal computer...just my work laptop, which is on high security lock down!
One of the few that actually left a message, albeit a robotic one. Wanted me to call a number (not the one the call came from) about my computer. Fairly sure it's some sort of scam.
