Unavailable Medication

I have been doing this the past 4 months or so. They send my RX to a pharmacy and they don't have it in stock. I have to call find a pharmacy that does have it in stock. Then try to get ahold of my provider to send a new RX to them so i can get it filled. They haven't responded and I need it TODAY and I can't get ahold of anyone. It's so agonizing, stressful, and frustrating. I feel so helpless.

My appointment is usally a week and a half before the RX can be refilled so I can't check before my appointment.
