Usual subhuman scammers with robocallers spoofing phone numbers - doubt this number is any more legitimate than any of the others they spoof. Report the scum to the FTC.
Have gotten several calls in recent months from this number or one like it. I didn't answer it and they didn't leave a message. I am on the do not call list and resent even having to go to the phone to see who is calling even if I don't pick it up. For whatever good it will do, I am filing a complaint.
