[Resolved]  Koryo/ Water Geyser KWN-S25 — Geyser leaking badly

I bought Koryo Water Geyser KWH-S25 from Big Bazar, Aditya Birla Mall Indrapuram on 22nd Dec2009. On 13th Jan 2010 we felt electric current passing into the water coming out from the geyser. We decided to switch the geyser off when the water is completely hot and then use it. On 15th Jan it geyser started leaking badly from everywhere. We called-up Koryo Service center n number of times everytime they said there executive will call and take an appointment. Till date no body called and no body turned up. On 30th Jan I went to Big Bazaar to file a complaint. The person there said an executive will come monday morning .i.e. 1 Feb 2010 and gave me his number. I gave this person a reminder call in the morning. He said he will be there by 1:00 pm. I took first half leave from my office waiting for this person. He didn't turned up. I gave him the call and he disconnected.
I don't know what to do now. Please Help.
