Got a phone call from this number. The caller left no message.

They will not stop calling each day mutiple times. I tried calling the number they are calling from and it says the number is out of service. I do not know how to get them to stop calling, any Ideas?

These people keep calling our law firm re our office move.  Advised them we are not moving several times and they continue to call.

These people keep calling me and when I answer there is nothing or no one there.  It is very annoying, they call up to three times a day.
