I Did not answer and they did not leave a message on my machine. Must be a "rotating" SCAM since others on here from last month said it involved lowering interest rates. Today my Caller ID stated "SURVEY".
Cell phone call and did not answer, no message left. Called back and machine asked if I wanted to be on a do not call list for this number press a button. Hung up.
Same as the rest. Called me @ 14:15 yesterday (which would be about the same time as the above posters' comments). Didn't answer. Voicemail recorded a silent message. Deleted & blocked.
