KenStar Air Cooler service center in pune

Summer season are on and it's really to hot in pune. i just purchased kenstar air cooler in pune two weeks ago from a dealers. Two weeks it run cool and i slept with a pleasure but now it is harsh to even slept without it. It was creating a noise in a night and i didn't bother after a bit later it's fan got stucked.

I don't know what to do as i am new in pune. I went to the dealer from whom i purchased this kenstar they said, " the fan has burned up , and no it will not contain any warranty.

So, if anyone knows where i can get it corrected then please do share over here
