Mahindra And Mahindra — amc contract taken at the time of purchase

I bought kuv100 in january 2018, i also paid for extended warranty and amc for 5 years. Dl 8cat 2422

Its been 2.5 years, i still do not know what is covered in my amc contract and what is not, everytime i send my vehicle for periodic maintenance they just change oil, oil filter and air filetr, for every other thing they ask me to pay.

Vehicles need many other periodic maintenance.

I need all the things needed to do and written communication of what there amc agreements cover.
