Whose responsibility is it?

This may be the wrong group so if it is let me know I’ll remove it. Basically I’ve lived in my house most of my life, multiple houses on the street are occupied by a lot of members of the same family and they’re desperate to buy my house but I’m not selling any time soon.

So there’s a number of children (aged between around 8 and 13) that belong to the same family that hang out on the street and over quite a long period of time I find that they’re vandalising my property. I’ve had glass thrown at my window which cracked the outer glazing, egg thrown at my car which damaged the paintwork, “niger” written on my garden wall etc. So at first I assumed these kids were targeting my house because it’s on the corner with an alleyway in between so it’s easy for them to “have their fun” and run, but I still confronted the parents who apologised and basically just screamed at these kids. Last week I was sat inside and a group of them were hanging over my garden wall and banging on the back door windows with a stick then running off giggling. So I walked round and I told the kids directly they better stop doing what they’re doing, one of the parents asked what happened and I told her, she said “oh sorry about that” and didn’t say a word to the children. Now today I’m inside and there’s two huge bangs at my side window, I went outside and a group of these kids are booting a football against my house. When I went out they just looked at me like that’s normal behaviour. I’m probably going to be told I’m wrong for this but I popped the ball and told them every time they do something to something of mine I’m going to damage something of theirs. They always look scared when I go out, they don’t answer me back they just point the blame at each other but it’s getting to the point now where it’s like who do I go to, I’ve told the parents multiple times and they don’t do anything, I’m assuming they think they’re going to push me to the point where I leave but that’s not happening, I’ve told the kids myself and it stops for a little while but that’s not good enough, Im getting so angry I feel like I wanna fight these kids and their parents (I’m pregnant so I won’t be fighting anyone but they’re pushing me 😅). Is it a matter for the police? The council? And if it is am I reporting the children or the parents?
