Who called from 4048915505

Calls my cell phone all hours of the day and night. Never anyone there when I answer. Never leaves a message when I don't.
There should be a way to block numbers like this.

Missed two calls this afternoon, no messages.

Same as all the other messages, called a couple times randomly, never does anything...?

Calls my cell phone - no message.  Don't know anyone in Atlanta????????

called my office but no one spoke.  I called back and a recorded message said "you have been contacted for telemarketing purposes.  If you would like to be removed from our calling list, please press 1".  Done.
