Caller claims its Microsoft saying they are informing me of repeated error messages coming from my computer over the internet to them...ya right. Caller is aggressive and persistent, doesn't let you talk much, like a script is being followed. Carried on too long and I got bored to find out how they wanted to scam me (wanted to ask for info so they can fix the errors of course)and hung up. VERY SURE Microsoft doesn't cold call about error messages LOL! Or wait, maybe they want to give you unsolicited tech support for free!?!
