Walgreens

Walgreens received my prescription on 7/3. I keep getting messages saying it's delayed. I called today and they said that they are not allowed to dispense this medication at this time. How is it possible that every Walgreens in Palm Beach County is on back order for them for a whole month? They gave me a date of 7/31 when they might be available. I have chronic pain and in the process of having all of my teeth removed. How can this be possible?
