My car is maruti eeco 5 str serviced on 22/06/2016 at your service center subh motors jabalpur mp vide job card no jc16003883 customer id [protected] and bill rs 9381/- paid by me. The service engineer name is mr vishnukant shukla. My car reg no is mp 04 cl 3050. It included the service of ac of the car. But after 15 days car ac is not working properly. I again went to your service center and contact mr irshad, he take 2 hours and not done any work and after talking to him by phone he told ac will replaced by new and it will charge 17 to 18 thousand. And if we not satisfied can complain to higher authority.
So please take my matter and repair my car ac as early as possible
Thanks
