I'm taking an expensive (tier 4) medication and have been taking it for years. My prescription is for taking medication every other day. I am being charged by Unitedhealthcare/AARP/Optum for a FULL 30 day supply (30 medications) even though I only you 15 per month. After over an hour on hold I was told that my prescription is for a 30 day supply - 15 times per month yet I'm being charged for a FULL 30 day supply (30 per month). This makes no sense what so ever. I just called again, was put on hold again and then transferred to a different number. Frustrationg to say the least
