Kolkata Police — Noisy neighbours playing loud music

I stay at Misme Apartment, near 3 number rail gate, kumarpara and I have been preparing for my exams. I have papers in just a few days and my neighbours in the next building are so loud when they talk and
the most unbearable part is when they are playing really loud music sometimes at odd times of the day and I can even hear sounds from their television. The man talks so loudly on the phone standing right in front of my window till 4 am in the morning. I have so many papers to write and it's very difficult for me to concentrate or even rest. Kindly see if something can be done about this. Thank you.
