Who called from 4153761448

Thanks everyone.  Skype hit.  Blocked it.

This number just started calling me. The first time was yesterday and now again today. If they knew who I was they would leave a message but obviously they don't.

If they told you it was about your student loan, JP, then it's for sure a scam.  I got a call from them and haven't been a student in over 40 years!  Received call 8-8-14 10:01AM caller "San Francisco"

I routinely block un-identified callers!

These calls are on my regular cell phone, not a smart phone. How can I stop them?????
