Called asking for donations to some type of Breast Cancer Fund - couldn't locate an actual charity tied to the number.  

Turned out to be a boiler room operation that gives less than 10% to the "charity".  That's probably why they also had their caller ID name blocked.  A REAL charity wouldn't mind sharing their REAL identity with the world now would it?

Stick with the real ones and leave these morons to starve to death in the dark.
