Maruti Suzuki India — Service problem

Address:

New Delhi, Delhi, 110035

I have SX4 which is always got service at Naraina Delhi service station. In last service I complained about Ac and Wiper blades in May 2016. Both issues were not resolved and now when I again gave my car for servicing. Service Manager is informed me that the they need to open the dash board to service the AC and even some of the condenser are also blocked. Total charges for AC repair is now more than RS 8000/-. Since my car have same problem again and again how would you charge me. It's a Maruti responsibility to take care of issues. Or else please suggest us the right service center who gives a genuine estimate not like the way I am getting shocks
