Vodafone — Noise pollution due to generators

I stay in Sneh Ganga Building situated on shankerseth road near vega center swargate pune. Vodafone has installed several huge generators at Vega Center next to our building. These generators cause lot on noise and air pollution. This becomes worst when there is power cut in Vega Center, All generators are switched on simultaneously and there noise becomes unbearable. Few days back they kept all generators on continuously for more than 2 days also at night. Because of this we were unable to sleep. Children were unable to study. Kindly look into the matter and provide us quick and permanent solution.
