Toshiba India — Toshiba 32 led

Address:

Mumbai City, Maharashtra, 400025

I purchased toshiba led tv 32 inches on 15 july 2013.
The product warranty is for three years. Picture is displayed but there is a slight change in color. This started happening since last 10-15 days. I am fed up trying calling customer care as they are not responding to my call. Every time when i am reaching customer care no their executive seems to be busy and they are keeping my call on hold for half an hour and then i had to disconnect the call.
