I read that you did, indeed. I think it's commendable and a whole lot better for your personal wellbeing than just lying back and taking it. Thing is that the best case scenario is that they'll say they never realised how their actions have affected others. It's however far more likely that they think you're being overly sensitive and that it can never be that bad. It's sort of similar to having a spouse who snores. You can tell them they snore all you like, they're not hearing it and they really won't know what impact it has on you. Short of you recording them, or them moving into your place while you go stomp around upstairs.

Your neighbour possibly already thinks that she's being as considerate as she can be, in the sense that not blasting music or watching movies, or walking around in heels, is limiting her in her freedom. She's not going to stop doing stuff she wants because someone else is hindered by it. It's the same type of person that blocks the aisle of the supermarket whilst having conversations with others. Those who run elbows first through a crowd to get a place up front. Those who talk through movies. They are oblivious to what effect their actions have on others.
