Cognizant — Lot of noise coming out of Cognizant Hinjewadi office terrace

Address:

Rajiv Gandhi Infotech Park, Phase-2 Hinjewadi

I am a resident of Tinsel Town Hinjewadi Phase-2, Pune. I am living next to Cognizant office. And there is a lot of continuous noise coming out of company's coolant. It has become so difficult for us to leave peacefully here.
I had complaint about this issue earlier through Tweet as well but got no rsponse.
Please treat this as an urgent request.
