they keep callng. i thought it was against the law to robo call now

They keep calling my cell for some woman that I don't know who that is. I tried calling back to the automatied phone phone and have them removed my number after they called me gazillion times and lft msgs. Well, the phone calls have stopped for about a month and now they started calling again. I have already indicated that they had the phone number. The frustrating thing is you can't speak to any life person. They are driving me crazy! If anyone has any solution, please let me know. Thank you.
