If I do not know the area code I do not answer & as always my instints are right because anyone who actually needs to speak with me will leave a message, these people never do. Funny they call me every begining of every month. My phone provider has no way for me to block the number. So I add their number to my contact list that I name "DO NOT ANSWER" & I choose either the silent ringtone or if phone has "Go directly to voicemail" option then so they can call all they long & I am never bothered.
Caller claimed he is from "Windows Operating System"(There is no such thing as Windows is made by Microsoft." Told him it is a scam and hung up, then went do donotcall.gov to report the number. Suggest everyone do this as the more reports of a numner, the grater the chance the FTC wil investigate.
