Discovery Insure Bad Service Received

It’s almost a month my car is still being assessed after I was in an accident. I was given a courtesy car but the 30 days is next week but my car has not been started to be fixed. I am kept on hold for over 10 minutes before I can speak to a claims agent. I have not received feedback on my claim unless I make the call. I am very dissapointed with Discovery. I expected great service but I’ve received the opposite. They haven’t provided the auto body with the authorisation letter but they require me to pay the access to the autobody. I’ve been trying to call today to get them to give the authorisation to the autobody but I’m kept on hold for long
