I am facing same issue. I had bought onida micro wave in Dec 2007. There was an issue with its door. So it will not get locked properly and will not start. I have raised the compalint with them one month back. one guy cam and had a look and said need to replace the screw and will drop by tomorrow. No news from him for 2 weeks. Not sure what to do. Everytime I call up the service center they will ask for 2 days to fix it up. Is going on & on. Is there any way we could escalate the same.
