Consumer Redressal

Sir, I have purchased one Micromax CANVAS HD A116 mobile on 04.05.2013. After purchasing I am observed that the screen of my phone is changing its colour automaticaly. Sometimes deep green & biue. So I went to the service centre at Sulekha More, Kolkata. The manager name is Mr. Manoj and the technician name is Mr. Sanjay. They repaired and handed over to me after 10 days. Then also I found the same problem. I again deposited the phone. Like this I have already diposited my phone for 3 times. Still they can not resolve the problem. Finally they told me that they can not help me more. The most important thing is my phone is in warranty period. I want to change the phone as this is in warranty period. You can call me to 8697236346. Regards, Saswajeet Kolkata Mob: 8697236346
