This was "Irene" offering help with "unsecured debt".
It was an automated scam similar to "Tom" from Home Security. You can always tell if it is automated by answering with weird answers. It will not reply in a normal way.
Auto dialed call with long delay before a woman came on the line calling to offer help with "unsecured debt". Told her I did not have any unsecured debt, she kept reading her script. Told her again, she kept reading her script. Told her a third, maybe even a fourth time, before it actually registered in her head. She then said "I'm sorry, you don't qualify for our program" and hung up.
Just received a call from this number, did not answer and they left no voicemail. I've been getting calls from (mainly northern) California on a regular basis but never answer them (all my friends are already in my address book and I don't answer calls from unknown numbers).
