Royal Enfield — Sold cheap local bike

I bought Thunderbird 350cc on April 2019. From the date of purchase i am facing issues. I take my bike regularly to service center for service. They provide very very worst service. This time I dropped my bike for service on June 24th 2021. Still my bike is with them and they are telling that parts are not available. More than a month my bike is standing in the service center. Cheap service response. Parts are very local. No proper response from them
