Even after requesting Humana to review the recorded conversation, Humana continued to bill at a much higher rate (at the old plan rate which is approx. four times the old plan). After being three months into the year and after getting bills (ofcourse at old higher rate), I wrote them a certified letter stating and requesting to resolve the issue urgently and CALL me to resolve. After one month I get a letter sending me the Power of Attorney (Humana's Power of attorney) for my wife. And upon calling them after four months and perhaps havings wasted hours on calls to Humana, today 4/26/11, they even refused to discuss the details stating the authorization is on records but they can not discuss details. It is perhaps the worst health care company once can think off regardless of the plan they offder. Not even worth considering when the intent is to delay it as much as they can. Imagine how great is the customer service when the can not even change the phone # in their records.
