I did answer when this number - caller ID SSI - rang as I was expecting an important call and sometimes the caller ID on calls (Social Security, for instance) can be unrecognizable. Anyway, the actual person on the other end gave me her name immediately followed by saying not to worry as she wasn't selling anything. The freaky part came when an obvious recording of my full name played when she said she would like to speak to... I said, "Not here" and she hung up. Glad to see from other posts that it is a survey company, but still concerned about the recorded name, which almost sounded like my voice.
I got a call from this number at 6:14 P.M. The caller I.D. said SSI. I didn't answer it and they didn't leave a voice mail. I blocked my number with *67 and dialed the number back. I got a recording saying that SSI is an independent survey company and I hung up. So much for the "Do Not Call List"!
I to got a call around 7:00 pm. They did not leave a message. But if i don't know the number or they don't leave a message then it must not be important.
