CVS review: Medication refills.

Its been several months that they have been unable to refill my monthly medication on the day it was due. Today its been almost 2 (maybe 3 weeks and they still CANNOT tell me WHEN it will be available). I get it every month, acetaminophen Cod. #4. What is actually up with CVS and a pharmacy that do not get prescriptions on time and a pharmacist who just acts like "So What"?. And the next month my prescriptions are totally date distroyed by the previous refill date.. I go through horrible physical problems each time this happens.
