Same. Which makes me wonder if the above posters are from a particular area in the USA -- I'm in Arizona. That would mean their calling machinery has our area programmed for their attacks this week.... It's always best to ignore calls from strange numbers. If it's someone who really needs to get in touch with you -- they will leave a message.
From Nebraska...Keep getting calls like this from all over the country. About a credit card payment being overdue or a car warranty ending but I have neither of those. Now I just answer and hang up within a couple of seconds.
Number not recognized, didn't answer, no message. Do not answer unknown callers since doing so puts you on an 'active phone' list for another time or place. Just let it ring.
No message when not answered; Called number got some BS about how you could get on their "Do Not Call List" ; Strange I am on the FEDERAL DO NOT CALL LIST.
