I get over 15 calls a day and they never leave a message.  When i picked up once they didn't say anything and hung up.  what can i do to have them stop?

They call several times a day and hang up when i answer. I called back and got a message saying "to leave a mess press 1, to leave a fax press 2 etc."

I get at least ten calls a day to my cell phone, nobody is there and they hang up when I answer but to call the number back it goes directly to a voice mail.  I even left a message with my number saying to stop calling it and to remove me from any list that I was on.

I started getting calles from this number 3 days ago and they will call me about 5 times aday and is driving be  crazy and when I call back all I get is something about leaving a fax . No one will answer and I left a message for them to stop calling me or answer the phone. But than no one did but kept calling and whne I answer, the person would hang up . What a JK!

I've been getting calls from this number for about a week. same as everyone else...call my cell, if I answer they hang up. if I call back it goes to voicemail.
