Neighbour harassing us day and night since 2 years

Dear Sir / Madam, I am writing this letter to formally request you to help me in dealing with an issue with my neighbour. The family I am complaining about - Lawangare, 3rd floor, Flats A7 and A8, New Giri Vihar CHS, Gokul Gully, Opposite NES International School, Nimbkar Society, and Pratiksha building (Home to MLA Vijay Joshi), Mulund West, Mumbai 400082, Maharashtra, India I have also enjoyed living in this colony for several years. However, for the past two years or so, I have been facing a lot of problems. My upstairs neighbours the Lawangares are making thudding and screeching noises every night and I have even sent the police audio recordings as evidences every night but the nuisance to me and my senior citizen parents just does not stop from upstairs even late at night and it causes me headaches, heartaches and even dizziness and more. Even during the day they wreak havoc. I have even sent the building secretary and chairman audio evidences regularly but nothing has been done about this since 2 years. This type of daily late night disturbance is not allowed in the apartment and particularly when sensitive people such as women and senior citizens are residing in the house beneath that of the Lawangares or anyone else. We have even requested this family thrice in person not to make noise so late every night to which he gave rude back answers and replies with twisted words instead of simply complying to our polite requests that would have made living here harmonious. Nowadays, we feel helpless and have had to resort to drastic measures against this family because they are continuing to be a nuisance. I hope that we can find a resolution to this problem as soon as possible. I appreciate your attention and thank you for understanding and support. Also, please note that they even jog on their treadmill any time they want, wreaking havoc in our house, rendering us sleepless and tired. They even keep dragging their furniture day and night and make some weird screeching noises probably with their collapsible windows or make some noise or the other just to disturb us constantly. Here is an audio evidence of the hammering noises recorded at 22.30 pm IST or so. I have had to amplify it to 48.5 decibels so that there is clarity - https://sndup.net/6ymz We are legally domiciled in the state of Maharashtra and our family traces back to the early 1940s and have been here since that time but still, we have to face harassment and discrimination by the upstairs neighbours, who have recently moved into our building unlike us.
