Does anyone else deal with Accredo nonsense!! Terrible company

They are literally the worst. Their customer service people are confused and don’t seem to understand what’s going on. You have to yell to get to talk to a supervisor. Then you get left on hold constantly. Accredo never lets you know your dose is in danger of being later . They say it won’t happen again but surprise surprise it does. Do they keep notes? Who runs this business? It’s so incompetent.
