This number keeps calling me and I would like them to stop.

ANNOYING!! CALLS BUT DOESNT LEAVE ANY MESSAGES!! CALLER ID SAYS RESEARCH CENTER!! SCAAAAAAM!!

Purchase a call blocker like SENTRY. It blocks the calls and you do't even hear the phone ring. Love it.

These people will not stop calling me.  Sometimes caller ID displays just the phone number and sometimes is "Research Center".  Either way, it's the same incoming number.  I finally answered the phone on a Sunday night at 7:45pm (after the 3rd call of the day) and used profanity and told them to leave us alone.  Of course, the woman on the other end of the phone didn't say she would because then I hung up on her.  

Who ARE these people?????

talk about the colletion data.
