This number called our house numerous times looking for my husband.   When I asked what this was regarding, they would not leave a message.  After numerous calls again to our home number I picked up and again asked them what this was regarding.  The man on the other end of the line would not say, only saying he was from "Eastern Research and that was all he could say".  I asked him to take us off their call list and he said he would.  Very annoying as they called 5 times in the span of 3 hours before I picked up a second time.
