Walgreens gave me generic Vyvanse under the brand name

My insurance is being gross right now and refusing to cover and I've been on the phone with them all day. They just told me that the last script they covered was for the generic. That bottle says Vyvanse on it as well as inside the Walgreens app.

So is this what they're doing now? Who do I report this to?
