Hyundai Motor India — Complain about service

Address:

Ahmedabad, Gujarat

hello, I introduce as Jignesh Chauhan. I have purchased i20 Magna option car from Pratham Hyundai (Sanand, Gujarat, India) in September - 2013. My car number is GJ 1 RC 5095. As per service schedule, I put my car for second service at Concept Hyundai, Ahmedabad in September - 2014. At that time I mentioned about my reverse gear problem but it did not resolve at that time. After some time I received feedback call from Hyundai and I mentioned same thing about reverse gear problem did not sorted out. After some day Received call from Concept Hyundai again and they pick up my car from my home to get it sorted and drop car at evening. but this problem is still not sorted out. I am very disappoint with Hyundai service that after 8 months still my problem is at same stage. Please advise me what I will do to get my problem sorted. Thanking you, Jignesh Chauhan
