Got a phone call that rang for a few times, then nothing.

When the call came in I declined to answer. No message was left.
ID was
'AMER CANCER SOC'
I have received calls from 12 different numbers that appear in the ID to be cancer fund related. Many I have blocked but then they simply use a different number to bypass the block.

I assume that if I answered they would claim to be a charity.

Received a call from 213-368-8533 and they left a message. On the message could be heard like a lion growling or I would say something demonic-like growling. Scared the crap out of me at fist. But I figured it was a prank of some sort.
