Ordering My Chronic Meds is made as difficult as possible every month

Every since month I struggle to secure my chronic asthmatic medication through Discovery's App - I have loaded my script, but because some admin person deems it not necessary to supply me with my Foxair, I am not getting an Order Failed - we cannot place this order as one or more of the items are not due for refill - DESPITE receiving a text message reminding me to order my new pump, as well as the fact I have 8 more puffs available to me. CAN SOMEONE FIX THIS ISSUE I AM NOW EXPERIENCING MONTLY WITH DISCOVERY. And whats good to note, I was about to give Discovery additional business e.g. my home structure insurance currently with Std Bank, but I think the constant issues with Discovery has clearly highlighted I need to take my business else where.
