Got a robot voice message on my landline that there would be a $300 auto-renewal for my “computer” and to cancel it, I had to call the number that was given.
The number is a toll-free U.S. number. I can't find any info, but it's been blacklisted on RoboKiller lookup as a scam number as of one hour ago.
The number is 1-844-978-0493
