Royal Enfield — engine noise typrider noise

Address:

Kolkata, West Bengal, 700024

I have 350 royal enfield classic from last 5 months i am facing problems with engine noise, on complaining they just service the bullet mobil change thats all again the noise comes.
Avik the service manager in austin kolkata outlet doesnot take things seriously after complaining thrice.
My bullet was kept for 12 days still issue not resolved.
Kinldy look into this as soon as possible as this time also they have kept my bullet for 5days but i am not paying single penny.
Warm reagrds
