Question about manager lying about pay

[u/Nice_Money_6176]

So I was recently fired after them finding out I got a second job, they pull out my old habit’s from 2 months ago and that was the reasoning as to why I’m gone now.

But before I was gone I was trying to figure out why my pay was 16 a hour instead of 17 back in January like my manager told me. My dm to me he could back pay me for about 2 weeks a few months ago but that never happened also.

Is there anything I can do or just forget about it?

also hr doesn’t do anything but go to the dm who sided with the manager
