Prescription medication nightmare

Yesterday (29/09/2022) my husband went to get his monthly prescription of medication (Venlor XR 150) refill. He went to Clicks Vangate and he was advised that the medical aid would not release the funds since the medication was a day early. After calling Discovery I was advised that the pharmacy dispensing the medication should call the PMB number on *** to resolve this matter and they should dispense the medication. Alternatively we could wait till today (30/09/2022) to go to the pharmacy and he should be able to receive the medication without hassle. So my husband chose to wait the day and go this morning, bearing in mind that he had accidentally double dosed one day and was left with no medication for today. Upon arrival at the pharmacy counter the issue arose again and after multiple phone calls to the PBM number this was not resolved. He had to pay for the medication out of pocket, despite their being enough funds in the medical savings and scheme rate. This is terrible service from Discovery. My husband is on anxiety medication and this whole affair has not had a good impact on his health. I don't understand how the medical aid can treat their clients so pathetically
