Xiaomi India — Regarding poor quality handset

I purchased Xiomi Redmi 4G from Airtel outlet on 14 January 2015.within 20 days from purchase i started facing issues with handset due to hanging and non responsive touchscreen. However, a week back the touchscreen became useless and i contacted to customer care who taught me few steps to reboot which was of no use. I then went to the authorised service centre however they close their shutter sharp at 6 pm. I then wrote to Xiomi India at service.[protected]@xiaomi.com however no one one bothered to contact me or even reply me. I then contacted me to customer care who again taught me few steps and advised me to contact s centre for repair. Hope to listen soon from them otherwise other options are open for the customers.
