They really treat their customers very bad. I had enrolled in the AARP Part D Plan in the enrollment period December 2005, Humana was alot cheaper at that time, so in the same month I enrolled in Humana. Now it is 2011, AARP Pard D was cheaper so I enrolled with them. They are now charging me for that enrollement in 2005 when I was with Humana and paid them. Since I have to be enrolled in a part D program, they are trying to make me pay for that. I called them and spoke to Kayle, she spoke down to me and treated me very bad and did not even care about the explanation or that I had proff of being with Humana and paid them for my Part D. Stay away from AARP, they don't care about you!!! It is all about getting your money. And since you are made to be in a Part D program, they do not care about your problems. Pay extra and go somewhere else.
