After having received more than 13 calls from this number within the past week and having reported the number to the FCC (I am on the Do Not Call list) I finally answered today. Earlier today, I had also tried to call the number back, to learn that it's disconnected.
The person on the other end claimed to be a man named Mitchell (or Mitch) Vera from the Rosen Law Center in Irvine, CA. Interestingly, if you call their phone number (949-363-6908), it's also disconnected. I told "Mitchell" I didn't think he was who he said he was and he became very abusive, asking me repeatedly whether I'm ignorant and yelling at me over the phone. I hung up on him and he tried immediately to call me back.
Here's what I decided to do:
1. Call the phone company. If, like me, you're with AT&T, they offer a call blocking service in cases of harassment.
2. Call law enforcement and let them know. This is not OK.
3. Update my FCC complaint to say that I think this number has been spoofed.
I got a phone call from this number, but they told me they were from the Home Retention Center. I asked them what the call was about, and was asked if I was late or behind on my mortgage, I don't own a home. When I told him that I don't have a mortgage he hung up on me. Also, the name he used was Mitchell.
