Hello Eva: I'm sorry you are having this ongoing difficulty. We live in an area of high-density housing & commercial establishments. It seems like there's always something going on. It seems like we're always calling the police for one thing or another. They're pretty responsive, for the most part, although sometimes they are helpful & sometimes they're not. Being awakened at 4:30 in the morning just has to make your whole day difficult. We seem to have that experience periodically too. It's never the same person in our case though. Typically it involves something that's going on at an office building nearby. Hope your day has improved since you posted this.
