Samsung Microwave Oven — Poor Customer Service

I have purchased a samsung microwave oven from Bangalore. After five months the product started giving problem. When I registered a comlaint with Samsung customer care, I was told that a part needs to be replaced. Even after a week I need not get any call from the service centre. I had to call back them and I was told it'll arrive on 15th Oct. I did not get any call from them till 21st Oct. When called back them I was told somebody from service centre will let me know the status. I did not get any call from then even after two days. I called them again and they told me somebody will call me in half an hour. Nothing happened. This thing got repeted atleast three times and nobody was able to tell me what is the exact status of the service. I had such a bad experience with Samsung customer care. They dont even bother to inform me when the servicing will be done. I dont know when they are going to repair my microwave.
