Royal Enfield — Disappointed with the parts of bike

Address:

Bathinda, Punjab, 151001

I have purchased classic 350 on[protected] and i have driven only 6500 till know and the chain of the bike has been damaged and makes crackling sound and i came to the agency and they said that it will not be changed in warranty.
I have said them on third service of bike also they said nothing will happen its ok... But know it has been damaged fully so i want to get it replace as the bike cost 150000 thousand and the part of the bike are so poor that at 6500 kms only the chain gets damage very poor quality. Please solve out this problem. Pb 03 aq 5533
