i have one voltas window AC, now after owning it for 3 years i have made it the purpose of my life to stop anyone from purchasing anything from voltas. the level of service they provide is unimaginably low, you can not believe the trouble these guys gave me. i even wrote bunch of emails to voltas and let alone resolving the issue they didnt even answer back. after putting up with the crap that was dished out to me from service center guys, i told them ill file a complaint against them in voltas, and guess what he told me? "go right ahead."
