We’ve tried the usual of calling police (three times), inviting them over to hear how loud it is (they agreed that it was very loud), asking to at least reduce the bass, blasting our own music (not sustainable) and so on. Sometimes it works for a day but inevitably it’s back to the usual.
Hoping for some petty revenge ideas to complement the other efforts.
