Consumer Redressal

I bought a whirlpool Ac on 3/5/2012 from Gopu Nandilathu G Mart, in Kochi, Kerala (Invoice number EKM-2096, Model Chrome 3 Silver, 1 ton). They fixed it on 8/5/12 but it didn’t work. So I complained to the dealer who asked me to wait and since there was no response from the dealer I contacted Whirlpool customer care through email. They offered prompt service but no one turned up. So i called up customer care on its toll free number again and again and I followed it up with their service personnel in Kochi and I received news one by June 30. Then they came for fixing it after numerous calls and follow up from my side on 6/7/12. The person who came for fixing it informed me that the gas is low and he will refill it next day. But the next day didn’t arise so far. Now the Ac works as if it is a jet engine with a roaring sound and there is no cooling effect. I want it to be replaced with a new one which functions clearly or my money returned, so that I can buy a competitor one.
