I finally quit

So the last time I saw my manager I had asked her to change a few shifts on the weekend. She had scheduled me outside of when I can get to work. So she told me that I’d have today off and next Saturday 1-6. This morning she texted me saying that I needed to get to work. I had told her that she gave me the day off and she acted as if she never did. I straight up told her I quit. I am so tired of her treating me like a child and fucking me over with the schedule shit.
