To start, the app is poorly designed. Instead of providing the customer service phone number, it directs the user to use the number on the back of the membership card. The number on the electronic card is not a hyperlink, nor can it be copied into the phone app. One either has to go get their wallet or take a screenshot and then click on the screenshot, which automatically turns it into a hyperlink. Also, this review feature doesn’t scroll when you’re typing, so it hides what you’re typing unless you manually scroll. That’s the “good” news, sadly. The worse news: even after having to deal with the obstruction of the AI voice menu, the agent could not tell me the price of my next refill. After acknowledging that part of the reason my first refill of 2026 was double what I usually pay because I had to satisfy the deductible (which I now have), she kept insisting that the next refill would still be the same charge and not only seemed incapable of grasping that the deductible is only satisfied once. I finally had to hang up on her. Finally, last year, Optum kept telling me that they weren’t filling my non-formulary med because there was no prior auth, but it turns out that they never requested one. This happened repeatedly even after they had an approved prior authorization earlier in the year for this maintenance medication. Even worse, they then hid the medication from my list so that I couldn’t even pay cash for it. This will all find its way into the grievance I am filing with CMS.
