Any phone number with a "555" prefix is a fake. Notice how in movies and TV all phone numbers are 555-xxxx. I have a fax machine connected to my phone line and when I see a number like this, I just have the fax answer it. Your number will be marked off as a fax line and you'll never get another call from that particular scammer again.
I received a call at 8:45 am this morning & looked at the phone number on the phone. I didn't answer. When I went the investigate the phone number, this number appears but not the number I saw when the phone was ringing.
