I keep getting hang-ups from this number every day, some times three times a day. They leave no message and I can't find any information about it.

Keeps calling not leaving a message!  If you are going to call leave a message, if you're not going to leave a message, DON'T CALL!

Different people from the same number called and left a message.  One was female the first day and then the second time it was a male voice.  I did not pick up either call.  The message was as follows, "Hello? Is (my full name) there? I'm looking for (my full name)".

Creepy voice, and quickly hung up and after I picked up.

I repeatedly get calls from this number. There is no name on the call display.

Calls daily.  Doesn't leave a message.  I have blocked it.

Received call this morning. No answer.
