I am a royal customer of yamaha and i make sure my bike is been serviced with authorised service center, by due to unwanted reason i have been cheated for charges not service for, i have been sub standards battery replacement, unwashed vehicle and been charged for service not done.

even after giving a estimate for 2400/- i have been charged 4458/-with out any intimation.

i want a refund for the same or would knock door of law and consumer forum.
