I called the number back, several times before it picked up. It sounded like an auto-dial, as no one seemed to be on that end, and it dialed several numbers, waiting a bit, then dialing again.
I have received several calls from this number. They always hang up when I don't answer, never leave a message.
I no longer pick up the phone AT ALL, as I am so sick of advertising calls. I let everything go to the machine. Have told family and friends I may not answer them right away, but it's better than interrupting something I'm doing, running to the phone, only to discover it's another one of those infuriating advertising calls.
I've been getting calls from this phone number and no one seems to be at the other end. Called back just to get dialing sounds without anybody picking it up. Help others reporting this phone number. http://www.privacyrights.org/fs/fs3-hrs2.htm
