Claimed to be repair on my computer, but couldn't tell me what kind of computer I had, I strung him along for several minutes, then he finally asked 'why are you wasting my time', I told him he was wasting MINE, and he should go F#*@ himself! Then I hung up. I have had 2 such phone calls and all you can do is block them. TO THE FCC: Why can't this phone number be tracked back and these people dealt with? Lucky I know better, but there are a lot of people who don't!
