User reviews for 510-399-0172
This number repeatedly calls trying to get an employee at our office. They never leave a message or name, and always hang up when I ask for details or that they do not call our office.
When an unknown number like the one 5103990172 is calling I never answer. I don't like telemarketers. If it was something important they would leave a voice message. But they didn't. I think it is another telephone ad.
