Who called from 6614341081

received a couple of calls, did not answer since it's unknown to me. They don't leave message.

Leaves a message on my machine:  Asks for me by my first name, then hangs up when I don't pick up.

Calls nearly every night. Tonight it was at 8:33. Never leaves a message, and I don't answer unknowns.

Called yet again. Daily from multiple numbers. I actually answered this time. And I was polite. If they call again, I will not be.

I got this last night, and the call id said Environmental Defense Fund.  I looked at the call log and it said the location was in Thailand.  Definite scam.
