Who called from 6104927303

Got a call from this number today (5/7/12) at 2:48pm.  Didn't answer, and there was no message.  Guessing it's another call from WCA telemarketers since I've got previous calls from 610-492-73XX.  How do they get away with calling people who are on the do not call list?

Wish these annoying calls would stop.  Aren't there laws to stop them?

This # has called me every single day for over a week now.  I don't answer as I am work and they don't leave a message.  How can you stop this?

have called me at least 5 times within the past 3 or 4 months..... annoying
