Mistreated badly.

It started fine when first joined. Now have discovered that they do not honor their authorisation. They give and then take back and am told that it is not worth the paper it is printed on. They do not respond to emails. Have requested a copy of voice recording. Still waiting. The authorisation was for an accident and according to them it turned medical. How does one know if it will turn medical with 5 cracked ribs!!!!
