Phone slammed on me when i called back

I have receiving calls from *** non stop for the last 2 weeks or so. Today when i finally called back a guy answered, i said \i have been...."he just said \""its one of our agents and they will call you back\"" and put the phone down on me. I am not interested in receiving any calls from now on as that was ****** rude. I have no time to be receiving calls and it being dropped as soon as i say \""hello\"".... SORT THIS *** OUT!!!!"""
