Caller ID said "Name Not Found". Did not answer. Looked up on free white pages reverse phone--says it is not a valid telephone number. Probably some scum telemarketer.
Said they were from windows and wanted to help me with my computer. A scam for sure as it also happened to my neighbor and a friend. beware, they want you to go to your computer and log in.
Since this is a fresh list, my guess is our telephone numbers were sold to a scammer that is the bottom feeder of scammers. I never answer as that tells them you are home. I block them afterwards and track them. My reward for spending my time this way is the phone does not ring when they call back, but I can see on the screen that they called. Such a pointless waste of time for all, however.
This has to be a spoofed number -- my area code is 770 but caller ID shows it as being Out of Area, although it can't be dialed as a local number either.
