Hero Motocorp — engine complaint

Address:

Thiruvananthapuram, Kerala

Vehicle name:glamour bs4 disc
Engine no:ja06ehh9k10078
Complaint details:
My newly purchased hero corp glamour is making unnecessary noices from the engine. This is making me feel unease about the vehicle and i went through a lot of hardships to purchase this vehicle. This sound is not good as far as i think. The motor corps told me it will go away on first service but still it didnt go away so i need my vehicle repaired or else i need my vehicle replaced on the earliest day possible... How can a reputed company like hero could be so irresponsible... So i need the things i mentioned done.
