Walgreens review: Prescriptions

I am very sick and my doctor wanted me to start certain prescriptions yesterday, to keep me out of the hospital, my oxygen is very low. They are a nebulizer, Methylpredisolone, Fluticosone/solon Disk and Levofloxacin. Prescriptions were not filled yesterday, and wont be filled today. They supposedly will be ready tomorrow. Why do I have to wait so long for my medications. This is unacceptable.
