Horrible neighbors, verbal confrontation, ongoing noise, very upset

I have been living in a luxury apt building for two years. My rent is paid on time, I follow all rules, and am cognizant of my own noise level (which is very low). A couple moved in next door recently and play their TV playing at very high volume. I left a nice note on their door. It did not improve so I spoke to management. The woman agreed to keep it down (their TV is mounted to the wall, which is unfortunately the one my bed is against).
I still hear the TV all the time, from 7am until late at night. I expect to hear some noise, but it is often extremely loud.

Last weekend, I heard VERY loud music at 8:45pm. I knocked but they could not hear. At 10:45pm the TV came on, at the loudest I'd ever heard it. I could repeat each word spoken, and could hear it two rooms away from the shared wall. I asked the security guard to come in so I had a witness. As we went to their unit, the woman came out. She introduced herself, and said "it's going to be a loud night". Both the guard and I explained that there are community rules and she cannot be disruptive. She refused to listen, stating that there was a fight on TV, she had company over to watch, and she would not change her lifestyle for anyone. She actually said she was being courteous letting me know they were going to be loud, and that management had told her it did not matter on weekends, and that I would "work with her" by wearing earplugs (most definitely not).

I had to be up at 6am to volunteer at an event raising money for cancer research and was unable to go to bed until 2am. The noise was intolerable. I sent two emails to the Community Director. She handed it off to her Assistant Director and has not yet spoken with me. The Assistant has been very nice and told me it would not be tolerated. I am up for lease renewal, so I would like to know what this means. It is too late to give my notice – I would have to pay 2 months’ penalty. There have been numerous complaints to management about this couple screaming obscenities with windows open - all summer you could hear them at the pool. Their upstairs neighbor has complained that they smoke marijuana with the windows open and it wafts into her unit.

I’ve run into her twice since. She muttered, “Bi*ch” yesterday and one morning yelled it 3x outside my door. We are adults living in a nice building - I feel extremely uncomfortable, afraid to walk to the garage by myself, and am extremely upset. I resent the implication of management that “quiet hours” are after 10pm. Do I have to live with excessive noise then during the day and earlier evening and being verbally insulted? I am a teacher and go to bed early/get up early.
