Lava Mobiles — New Mobile having issues

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201301

I bought a new Lava IRIS X1 Selfie phone on 30th Oct 2015 at The mobile store in mayur vihar phase 1. within a week the phone touch was not working properly when i checked with The Mobile store they asked me to contact Lava Service center. on 7th the phone handed over to serivce center till now the problem is not resolved. Is the company really doing Quality check.
