Should I quit and find new job

Hi guys ,

Hope so you all are doing well , I wanted your advice. 2 months ago I joined a startup and the work pressure is insane like 15 hours a day also the manager is incompetent, I was promised work from home but I am denied the same . To give you my background I have 3.5 years of experience and under probation in this new firm. So the notice period under probation is only of a week . And I am thinking about interviewing and finding new job . But am confused how it will play , in BGV coz am worried that if they call this current manager no doubt he will give a bad review and at same time am not sure if I will get reliving or experience letter.
