Thanks to everyone that posts onto this site. I, too, received a call from this number and they did not leave a message which suggests it was a scam call. Therefore, thanks to you al, I can put this number on my block list.
Called my cell phone. Didn't recognize the number so I did not answer, but immediately called back after turning off my show my caller id. Got a recorded message that the survey they were conducting was completed (1 min after they attempted to call me).
Automated message said caller was Green Study Survey Company, which searches show is a free cruise scam. As soon as I hung up had 3 calls from other robo-numbers within 8 minutes. I only answered this one because it was a local number.
Three evenings in a row at 6:30 pm they call my cell phone. I do not answer, and they leave no voice mail. This type of constant harassment must stop . . . . .
