Got a call. Answered and they hung up.

I called the number back and it belongs to World Vision. I sponsor a child through them, so they were either calling me about a problem with something or to raise money for the earthquake in Nepal.

Good to know! Thanks for posting

I also received a call from this number but did not answer it.  They did not leave a message.  However, after reading Jennifer's comment above, I too sponsor a child through World Vision - but my call was received today.

Thanks!  I too sponsor a child through World Vision.  I didn't pick up the phone only because I didn't recognize it.
