Who called from 8563690970

Called cellphone left no message

From Heifer International, as a charity they have the 'right' to call, but would prefer they don't.

Caller ID was "Bridgeton."  Presumed telemarketer.

said she was with 'students for life' or something similar.

Called my cell.  Didn't pick up.  They didn't leave a message.  If the other posts are correct and his is Heifer International, it's a non-profit for ending wold hunger and poverty.

I can't verify since they didn't leave a message, but seems likely.
