This is Donor Services Group calling on behalf of National Parks Conservation Association.  NPCA is, I believe, a legitimate organization.  DSG is a telemarketing fund raising company  that remits about half of what it raises to the charity.  Hang up.

This is getting worse, even though my number is listed on the "no call' registry.  In the last 3 hours I have gotten 4 phone calls, 3 I've blocked, and one that was unavailable with no number.  I love this site because while I wait to see if a message will be left, I look up the number.  I plan to get a new phone system that will allow for 250 blocked callers, 70 on my current phones (only 2 years old) just isn't cutting it.

They call several times a day.  Call comes up with NPCA.  I've asked them to remove us from the list, they still call our home phone several times a day.
