Withholding my check

I just left the job from hell a week and a half ago. 20 hours of unpredictable overtime every week and horrible management.

Now I was supposed to get my check direct deposit yesterday and I usually did on time every pay day at 7am. And now it’s the day after and past 7am and I still haven’t gotten a check.

I’ve been trying to contact them for days and no answer. What should I do? I have bills and a child. I already have another job, so that’s not the issue. I need to get paid for the hours I already worked.
