how the hell do i get them to stop calling me

Calls to my cell using my minutes.  Something about reducing credit card bills.  I pressed 1 to talk to someone and complain and it rang and rang.  Called the number and got a voice message.  Aren't these robo calls illegal?  How do I report them?

I keep getting calls from this number and they hang up when I tell them to delete my number from there call list and when i call it back it says to punch 1 to have my number removed from there list and they still keep calling they need to be removed from even using a phone

This number calls me ALL the time. It comes through my caller ID as "Phone Scam". They want your credit card #'s so they can lower your interest rate.  I ask them what company they are calling from or their name and they just hang up. IT IS A PHONE SCAM. I have contacted the sheriff's office and reported it. You can't call it back, it either is a busy signal or it says "this number has been disconnected". I am really tired of this. I even had a woman named Janice tell me, f*** you when I told her it came through my ID as a phone scam. Real nice huh.

That doesn't work either. They still call......
