Who called from 3057779790

According to the call blocking app on my smartphone, I've received seven calls from this number since 9/1/2012; the bulk were in the 5-8 PM range. Before adding it to the call blocking app, there was at least one call that got through & didn't leave a voicemail.  So, based on that, I decided to block it completely, i.e., I set the call blocking app to hang up immediately.

4/19/2012  I've gotten a call from this # 7 times this week.  No one responds when I answer the phone.

I don't know this number, they keep calling and don't leave messages. Boards indicate they get the same call from people claiming to be from comcast

Stop having this number call me.  Its not SECURE

BEWARE! Calls from this number come through on Caller ID as Maroone Nisson, however, male with hispanic accent claims to be from Comcast and wants to assist us in setting up our digitial service.
