It sound like you are a customer who is dissatisfied with the product you paid for. Don’t buy it anymore, would be my recommendation. Everyone knows UHC is basically worthless insurance, buy something better.
And if you’re mad at someone, be mad at your state’s insurance commissioner . Google who that person is and complain to them.
They have the power, with the stroke of a pen, to decide what kinds of plans can be sold in your state. Too bad all of them are in the pocket of UHC Anyway. They make $120k/ year, but if they go easy on UHC while they’re serving, they get $500k/ jobs doing basically nothing.
