Grossly *********** - 4 incorrect claim processes in a row

I have never come across incompetence in my life like this. They have processed my claim wrong four times in a row. The agents are either untrained or ***********. Every month is the same long process. The latest case is they don't pay when I have the medication approved and then an agent tells me it's not part of my benefits. This is not the first time I have complained here either, it's the only way you get a response. Disgraceful.
