Manager wants me to come in for last 2 days because they have no one else even tho I quit

So he keeps spam calling me and telling me to atleast finish these last two days because they have no one else. N that I can’t just “quit like that”. I really don’t want to but my morals are telling me to. Should I just sleep in? I’d have to walk 1 hr and 30 minutes to get there and walk back home another 1 hr and 30 minutes because I currently don’t have any transportation and the job sight is different from the one I applied to and was promised
