TVS — Self start issue

Hi, I bought my TVS Jupiter in january 2021 and facing issues with self start from March 2021. Showroom mechanic said that you have to run you bike atleast 7 to 8KM per day to make the Battery healthy for self start. I want company can check this issue if this is genuine as it was not discussed with us at the time of purchase. Please suggest how this issue will be fix and by whom. My bike is on guarantee period
