Lenovo — Worst service center and slow process

Address:	New Delhi, Delhi, 110020
Website:	lenevo.com

I have submitted my phone to lenevo service center in okhla. its been more than 10 days and now they are saying it takes 10-15 days more.
its a worst service ever i got. they say if i can purchase the things from own then it take one day only but in the warranty they takes more than 1 months.
what the hell is this.
executive working over there is not relevant and poor facilities as well they work very slow.
their services are worst and their focus on making money rather than customer satisfactory..
