They didn't leave a message.  The caller ID showed Unknown Name.  A callback on the cell phone got a recorded message that said they were a market research company and "therefore not subject to NO CALL lists".  The recording DID NOT mention the name of the company.  Hiding the call ID and not mentioning their name on callback,.HUH, .....................no doubt totally legitimate

This time a callback said I had reached a "pinger number" and could have my own pinger by going to pinger.com.  Amazing how they morphed from market research to a pinger in only a week.  No doubt it's all totally legitimate...............NOT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!   They didn't even name the company on their recording.

Got another call from these morons today at 4:25 p.m.

Been getting calls for the last several days but never answered.  I just got a call but they hung up as soon as I tried to answer.  Calling back gets a prerecorded message.  Informs that you can opt out by talking to an "interviewer".

Tiffany calling on behalf of US Dept of Ed.  A scam no doubt.
