Please think twice, If you take any place where Duserve provides chilled water and ac service. The management including the customer service is nothing but people who just don't want to take any action other than telling you that soon they will reach.
My ac is not working from almost a week now and I sent 4 emails, apparently they found out that I have a problem on my second email. The apologised and said soon they will approach me, then I sent another then I sent another email. Total of four emails sent each from myside but nobody bothered to have my problem resolved.
