Hyundai Motor India — battery of creta diesel car purchased in february 2016

Address:

Pune, Maharashtra, 411040

I have purchase a creta automatic diesel car in february 2016. My registration no is mh14- fm 119, last week 3 times road side assistant came & jump started the car, while charging the battery again & again he told there is 3 years warranty for battery, take the car to service centre.
But as soon as i took the car to service station, sanjay hyundai bhosari person refused to change the battery.
Please replace my car battery, as it is under warranty & website for hyundai car for parts also shows there is 3 years warranty on battery?
Please look into the matter urgently or i have to forcely go to consumer court.
