Didn't answer.  Caller ID said "Donor Relations".

Called on a Monday evening at 8:30 after a very trying day at work.  No message left.  Big surprise.  If they call again, which I'm sure they will after 8PM, I will block their number.  I only get 12 block numbers through my greedy phone company.  I hope these m-er f-ers burn in h*ll for scamming people.

Caller ID says Donor Relations. I answered. (I actually thought it said "Your Relations" and I figured it was a scam I could have fun with.) The man says "may I speak with the man or woman of the house". I countered with "No". There was silence, but not the silence of a dropped call. It hit me, he's recording this. After a pause he says "are you still there". I almost said yes, but I remember reading about those scams where they record you, take the recording of you saying yes, and attach it to a recording of him asking if you give approval for some monthly charge against your phone bill. When I didn't answer he hung up. As a fundraising professional myself, if he truly was with a charity it was bad form to ask for the man or woman of the house and not the donor by name.

Any legitimate charity will list their own name in caller id.

They called again on a Tuesday evening at 8:30PM - had to use my 9th call block slot out of 12 that i have through greedy centurylink phone company.  I'm sure they will only use a different number next time to get through just like the alleged fraternal order of police did - they used about 5 different numbers.
