Trending @Infosys; Weekend work support on notice period

Due to continuous 24/7 work, I resigned and am currently serving my notice period. Even now, I am being asked to work on weekends so that I can be utilized as much as possible. The project is expected to go live in the next 2 to 4 months. I have requested an early release, but my manager has not given any clear response so far. I am also unsure what will happen to the unutilized comp-off leaves. Has anyone faced a similar situation or can share how best to handle this? Any guidance would really help.
