These scumballs are General Contractors doing work in the area using a spoofed phone number trying to rip off the consumer. Don't give them the time of day.
Someone's been calling me with this number. I received two phone calls from this number two days in a row; calls but they do not leave a message. I did not try calling back.
This number usually appears as an Unknown caller because the phone lines that are associated with this number are from a high-security office. If you know someone that works for the government or Boeing or some other high-security company, it could be that they're calling you so pick up!
