I answered it and the guy on the other end said he's from Red Cross?  I assume he is asking for donation so I said I am on my way out and he said he will call back later..

They call me like 4 times a month its annouying and yea they never leave a message so i just ignore their calls

These people keep calling and I don't know who they are.  Never leave a message and when you pick up the line seems dead.

Someone keeps calling me from this number in the late evening.

this number called me at quarter to 9.... no message

Red cross, yup!
