so sorry you're going through this, i can relate and understand your frustration. i also had problems with my drs office, and when i was denied last minute-it was like i no longer existed and niether did the hernia that they were going to repair during my surgery. i had to figure things out on my own and after many months-i've been approved, even though my surgery dates alreay been changed (again) and i'm still trying to figure out RNY or sleeve. (there's a longer story there) but basically i just want to tell you there's hope-keep at them until they do what needs to be done.
wishing you well
