Posted quite a few times about my neighbours on here so I must seem like quite the curtain twitcher 
Honestly I'm not (that) interested in other people's lives usually but just looking for a bit of advice on how I can approach this. We've been having an ongoing dispute about their grown up kids putting food in our recycling bin leading to it not being collected (by ongoing dispute I mean we raised the issue and after them being completely rude and aggressive now they avoid us 
) for the past few months and I've also mentioned in previous posts about them having extremely loud, base-y parties when thier parents are away but we've never complained to them or about them regarding this despite it being completely intolerable levels of noise.
This weekend it looked like thier parents were away and the music started about 7pm, not long after putting my two year old to bed. It got progressively louder over the course of the evening, the noise in our back garden was awful and there was quite a lot of people in the alleyway behind my house running up and down making a fair bit of noise. I told myself I would knock at 11pm if it didn't quiten down by then.
Knocked at 11, explained I had a toddler next door who was being disturbed by the noise and they said they would turn the music down. They didn't. Knocked again at 2am as the music was louder and people were standing in the alley outside our bedroom window screaming and shouting. There was also people in the front smoking pot underneath my daughter's bedroom window. Again they took no notice.
Their parent's cars have reappeared on the drive this evening. I'm still steaming over Saturday night and I might BU but I'm dying to speak to them. My question is what would you say (if anything), given that they haven't spoken to me or my family for a good few months? Would I be right to confront them? I really want to contact the council but my partner thinks IABU!
