Consumer Redressal

I have purchased LG Microwave oven in 2010. On 22 Dec 2014, it became unserviceable. I have lodged 4 requests to LG Customer Care for repair since 23 Dec 14, But till date, no one has visited my residence to repair. I have spoken to allmost everyone in LG, like Area Manager, Service Centre Manager, Servive Centre. All of them assured every time that my complaint will be adressed at the earliest. But till date, there is no progress. Its a great inconvenience for me without Microwave Oven as my husband is in Defence and my sons are studying. Please intimate me how to resolve this and whether I can take this case to consumers forum. Regards.... Rajlaxmi, AFS Tambaram.
