Godrej Appliances — Fraud brand not providing service in warranty

I have purchased a godrej refrigerator and have been taking extended warranty from brand regularly but the brand is not bothered to provide service. I have issues with my refrigerator and have been complaining since long time but they say just technician will call but nobody is calling back. Pls get this resolved at the earliest or will take this to legal authorities as I have my extended warranty proofs.
