Sony India — problems coming again and again in sony handset,no help

Address:

Gautam Buddh Nagar, Uttar Pradesh

Again there is a new problem cropped up. I don't know what to do. I received this phone from sony centre today and after some time I came to know that it's microphone is not working and then I again went sony centre, they did nothing just updated software and now still the problem came up. It's too much now. Please tell them to ask their higher authorities to contact me. I don't want to talk to anyone. I am fed up of Sony. Or I am going to the consumer court. Will see sony people there. I want my money back. I am so unhappy and sad
