You might also want to approach her husband while he's walking the dogs, just to see if there's anything you can do to help remedy the situation. As I said earlier I was literally in the exact same situation as you (car work, complaints etc) and decided to approach the husband. He turned out to be mad chill, and more or less told me to forget about the bitch and just let her go mad. I even told him "look im willing to work with you guys" and he more or less said "there's no working with her, don't worry about it". We've been friends to this day. Crazy,Old,Wealthy,Women....god help us all.
