CVS review: Picking and choosing who gets their prescription filled

I have been using CVS for 20 plus years and NEVER had a problem. I had to transfer my prescriptions to the pharmacy in Hughesville due to the fact I have moved and I have been having nothing but problems. I get my meds on the 18th of EVERY month, I always have. EVERY month now for the past year I have had problems, I have delt with having to explain myself EVERY month. NOW my prescription for a certain medication, they were telling me that they have NONE and don't know when they are getting any and I have told them I would keep checking back, I called them the morning of June 27th and they said they still didn't have any. My Husband gets the SAME medication and he was notifed 1 hr later that his was ready. Now mine only call for 20 pills and his calls for 60 so I called them again and they STILL told me they didn't have any.. REALLY.. So I asked them how that was possible, and after getting upset they "found a bottle" on the top shelf so they will fill them, after 10 days past my refill date. How are they allowed to pick and choose who gets what?
