Consumer Redressal

I am suffering since I bought Whirlpool Window AC 1.5 ton in Apr 2012 through Big Bazar Faridabad. After buying the Whirlpool AC, it stopped cooling within a month. I kept calling Whirlpool customer care and it took around 2 weeks to Whirlpool engineer to come. After diagnosing the issue, he found the GAS LEAKAGE problem. After filling the gas in Whirlpool AC, they said with guarantee that it will never leak again. After few months, the Whirlpool AC stopped cooling again. I called Whirlpool Customer Care and Whirlpool Engineer came and found that GAS is LEAKED AGAIN. The GAS was filled and they again promised that that Gas Will Not Leak Again. Now the GAS is LEAKED AGAIN. As the gas is leaked thrice within a year, it clearly shows that the Whirlpool AC given to me is of very poor quality. I kept calling Whirlpool customer care and sent them many emails, but they are not listening my kind request. Please make Whirlpool REPLACE THE WINDOW AC IMMEDIATELY.
