Be careful for all retirees, my husband insurance ...

Be careful for all retirees, my husband insurance got revoked forever. When he retired by July 2015 we were told that he will have his insurance forever then we were told that we don't need to do anything with it, we will kept our coverage lifetime but by 2017 it was revoked. I tried to filled-up the form for an appeal till now 2018, they sent as the note that his appeal is "Denied". I've been calling them but it seems like these people doesn't care, there's no one could help.

He served for 20 years, and this is what he gets. Insurance revoked forever.
