Mystery Solved. These calls are NOT coming from The Heritage Foundation. They almost certainly originate from telemarketer The Heritage COMPANY. http://www.theheritagecompany.com/
Heritage foundation solicitation scam. Call at all hours even after you just renewed your membership. They can kiss my [***] if they think I'll ever donate again and I hope you will tell the dizzy [***] solicitor the same thing. I shouldn't take a ton of money to do the right thing and the Heritage Foundation has lost my and my family's support.
Give Right telemarketers calling on behalf of Heritage Foundation. The rep I spoke with when I called was nice and said they would remove my number. It is very sad that any organization turns to telemarketers, Heritage Foundation lost my respect.
