Microwave Ovens in India

I own an Onida Microwave oven. I purchased it in Jan 2009. I fell in love with it the moment I saw it. And the features were good too!

The honeymoon ended when it first started giving problems within 3 months of purchase. The inside light and the turn-table stopped functioning. After giving a complaint, it took 2 weeks for the service executive to come and identify that the PCB is faulty, and has to be replaced. It took one month after that and about half a dozen email to the customer care email ids for the PCB to be replaced.

That was not the end of it. The oven stopped heating a month after that. The calls started again.. This time, they took only one week to come and identify that the magnetron fuse was blown. The guy promptly replaced the fuse with a wire and told me that he would replace the fuse the next day.

Its been a month now, and still no on has come to replace the fuse. I've already called them 10 times..

I sometimes wonder why the service industry in India is so bad. Is it homegrown companies like Onida only, or others like LG/Samsung/IFB also are the same in case of Microwave ovens?
As of now, I'm confused which microwave oven is the safest to buy in terms of product quality and after sales service.

Can anyone advice?
