DO NOT ANSWER PHONE....DO NOT CALL BACK....THEY DON'T CARE..
THEY ARE FISHING FOR VIABLE PHONE NUMBERS AND WHEN YOU ANSWER THAT JUST VERIFIES YOU OWN THE PHONE......DON'T PRESS "1". Either . That lets them get more info....they then sell your number to other companies and you wind up getting more calls. It's annoying for sure but just let it ring, after awhile calls will decrease....I only get maybe 3 a week. Now...just steel yourself, don't answer, check your caller ID. Most of the time they are robocalls....why do you think most don't speak.....they just want viable numbers which you give them when you answer or call back.
Don't have caller ID on the upstairs phone, so I answered when it rang and it was a guy who assumed I was my aunt, addressed me by her name. I told him I was who I am and that I represented her, who is calling? He said, oh, I'm sorry, I didn't realize I was calling her in the office, thanks, and disconnected the call and I got the same rapid busy signal that I got when I called the number back. My aunt is in her 80s and has Alzheimer's, and doesn't live here, but my number is her contact number. This 415 number is being used by scam artists, and Pac Bell is doing NOTHING about it. I live on the bloody east coast and a few years ago, I had to bug the cops in my town (before I had caller ID) to find out what number was calling me and hanging up on me at the same times every day. It was a Pac Bell number. My cops took care of it; their local cops wouldn't touch it. When it happened again a year later, I had the number the officer used in his report and I called it and got this nasty woman. I get a lot of hang up calls from California and I've had it, I'm on the Do Not Call List, and it means nothing.
