Sir/madam,
I had purchased sz rr version 2.0 in blue and white colour in april 2016 from yati yamaha patna, bihar. By delivering my bike the sales man drop my bike on inclined and get scratched on fuel tank, cylencer, saree guard, back side body. I ordered them to change the damaged part. They do so but their response was irritated. On first service this has untrained mechanics they rubbed my bike by sand paper. For removal of water stain on back body. That part has been faded. They do not give any response to it. And in second service on 8 july 2016 i told them that check my bike's chain case and chain either it is loose or not. The mechanic whose name is suraj tighten my chain hardly that i ride on my bike and my rear wheel get very hot.
Can i ask you why your company give job to untrained mechanics.
I think i have wasted my money on your company.
They have no manner to talk to customer. Not give response.
Money never grow on trees. My parents work very hard to earn money. And your company sibling doing these type of nonsense things.
I surely not suggest any of my relatives and friends to purchase yamaha bike. If i don't satisfied by company's service.
I request you to please contact this dealer to correct their behavior.
Next time i want all these things as good as possible.
