Receive many phone calls from 1-417-800-2511 asking for Japanese male 18 or above to participate in a studies. My number is unlisted and registered with the 'do-not-call' list. The rep on the phone was unable to clarify how they get my number.
caller id shows it as TRG Polling; and, they'll give you a "gift" if you answer their "questions": just hang up if you happen to pick up the phone without looking at caller id.
My call was from TRG Polling. The voice mail was an offer to lower my electric bills if only I would press 1 or 2 or something. They really wanted me to do that, because they told me to about 5 times. I was also given the opportunity to remove my number from their call list if I pressed 5 or something. Yeah, I'm sure of that.
