Who called from 4045199133

I answered the call at 10:38am nothing but silence, I recalled the number and the message was this number has
been dis-connected.   what can I do to stop the callings?

Got call very early in morning.  Stated "Don't hang up - this is not a sales call.  The government has new plans for student loan..."  I hung up. Not a sales call, yeah right.  Just an information gathering call - my personal information I bet.  I will block this caller from now on

Get this call al the time, how can I block the number?

Just called me, I rejected call, no message left.  When I called back 10 minutes later, it said 'This Verizon wireless number has been changed, or disconnected'
