Suzuki Motorcycle — delayed service support

Address:

Faridabad, Haryana, 121003

After using my gixxer for 15000 kms only, it had started giving me severe engine noises, to rectify which, i gave my bike to a-one suzuki service center, faridabad on 11th nov. As of 10th dec, they are saying that they need 1 more week which they've asked for thrice already. Disgrace to japanese brands. Also, mailing them is like talking to a wall.
