playing with patients health/life

My wife has an autoimmune condition called lupus.she needs her meds daily to enjoy a good quality of health.its taken a long time to get her daily dosage Correct.its been 2 weeks that she has been without meds.she is now not feeling well.No forewarning of meds out of stock or even a script to visit local pharmacy to tide her over until stocks received.I'm sure this is in breach of medical schemes act.very angry as we are paying exorbitant premiums.we had to phone them to find out what's going on
