Hero Motocorp — Defective Bike need replacement

Dear Team,
I have purchased a Super splinder bike on 10th of November.I am very much unhappy with the product. I am becoming a regular customer for your service centre as bike defecting regularly. I have purchased for my official purpose with my all savings. As I am a sales person my bike is very much necessary for me in this Covid Situation. I have taken this new bike for my old faith on HERO. I am very much hopeless with the product. It also impact my job.

However last 15 days my bike is there in your service centre and Hero service centre is telling me there has a issue with the engine so they will send it to their Super distributor point, that meant I have to wait again more then 15 days.
My concern is I want to replace my bike immediately because my old bike is defecting regularly. Please help to rectify the
