Harassing Phone Call

Received a call from someone named Amanda claiming to be from AMG Mortage. I interrupted her and told her I was not interested and to take me off her call list. She told me no, that she would not take me off her call list because i was "rude".  I asked to speak to her manager and she said ok... hi, I'm calling from AMG mortage and I am the manager. She was so smug and horrible. I hung up on her and blocked the number.
