need a new card for med supp HD plan F. This is a terrible system.

I need a new card for ned supp HD plan F. Please call number above. This the worst contact system for paying members.

The phone number on the back of the card hangs up on me. There is no phone # on website. I don't want to see other people's problems with you and your lack of responsiveness.

God forbid, I should need your help.
