I have gotten calls like that as well. Some voice recording saying they need to serve papers or something. I block that number then a day or so later the same voice recording same women calls from a different number! Wht the heck??!!
>>> Me too! I blocked the number bc all it shows up as is 304! How is that possible? <<<
It's the Spoof Fairy calling to leave a message under your pillow.
Seriously, if the number being sent as caller number ID is 304-000-0000, then the number is either being spoofed, because the digit after the area code has to be between 2 and 9, inclusive. Either that, or the number is a foreign number that will not display on a caller ID unit made for use in North America. (Phone numbers outside the US can have fewer or greater than 10 digits.)
If all you see is 304 (and do not see zeros after the 4) then possibly the number is spoofed AND the caller ID unit is not working properly.
No matter what, if you get a call from this number purporting to be a "regular" caller asking you for any kind of information or money, the odds seem overwhelming that the caller is a scammer.
My wife's cell got a call from this number at 2 a.m. (I got up but missed the answer) I then got a call at 12 noon the next day (from this number) and when I answered it stated "Your MasterCard has been hacked, Press 1". I pressed 1 (which I shouldn't have done) and nothing happened. I have a dumb phone so I don't think I got a virus. My wife and I have adjacent phone numbers (last digit of her's is 5 mine is 4 all other digits the same). So I don't know their calling pattern but it not sequential.
This # started callin today out of the blue. Finally after 4 times if them calling some guy said his name was mason fron international bank but gave no other details as to why he wanted to speak. Scarey thing is I only have one bank and its not international. Oh n this guy knew my name
