Hyundai Motor India — Service Issues

Address:	Gautam Buddh Nagar, Uttar Pradesh, 201301
Website:	Hyundai

My Hyundai car is having problem of RPM ups and downs. I have visited Hyundai service centers for 3-4 times in Noida, Baraut, Saibabad but my problem still exists. Last time i have done my car serviced at Hankook motors, Noida and i told them about rpm problem it didn't get resolved after service too. I also raised a concern at Hyundai service feedback but no representative called me for the issue. I am suffering from this issue from last 4 months and didn't get any resolution from Hyundai. Car average has gone down to 10 Km/l and is 2013 model but its performance is like 5 years old model. I am not convinced with the quality band service provided by Hyundai. I need proper repair and refund of my last service as nothing is resolved.
