My grandmother receives a call from this number multiple times a week.  They ask her if she is looking to remodel her house and try to sell her different home-remodeling products or packages.  She has asked to be removed from their "calling list every time, yet they continue to call.  I called the number back from her caller ID and it was a number that was disconnected or no longer in service, so something does not seem right.  I think they are some sort of group that takes advantage of the elderly.

Anyone know how to find the actual contact information for a company like this? I'd really like to stop this from happening to my grandmother.
