I've been getting calls off thsi number also. Its from 2 evolve a fundraising agency who partner with different charities if you email contact @ 2evolve.com.au someone can remove your details.

Medecins sans frontieres, just calling to thank me for my donations. They call night and day until they get through. They also send postal and email updates so this just gets a bit much. Sometimes I consider not donating anymore, if the money is going to staff costs on calling all of these people who don't want to be called!
