I just received a call from this number. There were boat sounds in the background as a recording said, "This is an automated survey, and if you complete it you will receive two free tickets for a cruise______." (I didn't catch the name). They wanted me to press one to take the survey. I hung up and did a reverse phone number lookup, which revealed that this is a cell phone in Pittsburgh, PA, purchased through Sprint Spectrum L.p. I know I'm registered on the national DoNotCall list, so this is probably some sort of scam.
I just emailed Sprint to see if there is someway the person calling and soliciting from this number can be stopped. I informed them there are many complaints about this number. Hopefully they can do something.
