Taco Bell review: unlawful discharge

I was employed @ Taco bell since 2004, in the last couple weeks the RGM Rebecca Schnell quit for another job. So Lori, a taco bell supervisor took over the scheduling and wasn't very good at it. Other employees complained about the random scheduling that is usually posted on a Sunday or Monday. I work three days a week Mon, Tue, Thur.. Last week I needed those days off for family issues so I requested all three days off in the request folder. I go to pick up my check the following Tue, and was told I'm off the shed.. permanently for no call-no show on the days I requested off. "Everyone who request off ahead of time like I did always gets the time off at that taco bell" We were arguing in front off customers and employees over the fact and conclusion that she didn't know my name obviously, cause when I told her to go get the request folder, which she said I was NOT in, I showed her all 3 days I requested off. She looked very shocked & appalled to see that she was the one to make the mistake. I'm all-ready off the schedule now, so I am going to file a complaint to her superiors about this matter. I don't believe I'm at fault if a manager/supervisor can't read or doesn't know the employee names.
