MRF Tyres — complaint for replacement of tyre and against dealer shree hari tyre dealer in nadiad

I have purchased my yamaha r15 bike in april 2019.
From the day of purchased there is a major issue of leakage in rear wheel. From the same month i found this issue and after 2 months i have started process. Yamaha informed this issue to dealer in shree hari tyre district kheda gujarat. They have kept bike under inspection for 15 days. But issue not resolved.
They again i started process. And today (25th jan 2020) i have issue letter for tyre replacement from yamaha and i went to mention dealer. He told me this process will take 15 days. But you have to give me tyre. So i told then what should i do? I should hold bike with my hand for 15 days. He told it is your problem it is not our problem. Is this a way to give answer to our customer. I felt very embarrassing after listening this answer.

So register my complain against dealer and please do needful.
