Called the number back after they called me and left no message. Got a recording that stated they are SSI (Survey Sampling International). No option to opt out of having them call on the recording.
I've gotten two calls from this number, when I answered the first call no one on the line, no recording, nothing. Second one I let go to vm, no msg left. I did a reverse look up and it said it's an invalid number.
Caller identifies itself as SSI
