sell a house fast in Lees Summit

I am a 17yo who recently lost there mother due to Covid-19. I received a call from them today asking for my mother. I then told them that she had deceased and that she was talking to her minor child. The man who called me then proceeded to try and hound me with questions. I repeatedly told him that I was a minor and that my mother was deceased. He continued to hound me with questions regarding her house and her. He did so non stop without sympathy. He told me her house was about to foreclose and I then told him that we had a buyer and wasn't interested. He continued to push. After a while of trying to play nice I told him that he was harrassing a minor about his deceased mother and that I was unable to help him. He then said," we are just trying to put money in your pocket." Playing on the fact that I was the child. When I told him that I was about to hang up and to not contact this number again he said," fine I will just contact someone else." He then proceeds to contact my aunt.
