Called on my cell phone, which is registered on the National Do Not Call list.  When I tried to get out of him which computer he was calling about, He said "Windows" Duh! they're all Windows computers, ya dork.!  Anyways, I told him he didn't realize that he was calling the IT person for my business and that what he was saying was incorrect. Boy, did he hang up fast.  Really kind of rude. I was just trying to help the guy out...LOL.  Bunch of scamming jerks!!!
