I visited service center today to get delivery of my R15 V3, Which I gave them to service and change spare parts. I was shocked after seeing my bill of Rs.30, 677. This number didn't shocked me what really shocked me is following
1. They are charging more than MRP on some of spare parts
2. They are not providing a GST Invoice
3. They are charging too much service charge.
I am attaching the invoice provided by the Yamaha Bike Corner/Service center.

I only want a genuine bill with MRP.
Over-charging is also considered to be an unfair trade practice, as defined under the Consumer Protection Act, 1986.
