Liberty does not help in anyway!

Since being on Liberty I have had to pay more medical bills in 2 years than I have paid in my entire life. I was in car accident I then went to Sunward Park Hospital when we phoned them they said they do not cover Sunward Park so I had to go to another a hospital, fast forward 3 months, I get medical bills from both hospitals as they did not pay any thing because there was no Authorization number. Fine I paid all the bills. I then need to go the specialist I phone them and find out what I need to do to go to the specialist as I will be going a lot as I am pregnant also everything they cover in pregnancy. All information that was given was that I need a referral letter and Authorization every time I go. Nothing about everything they cover. I have been twice to the specialist, first time I went I paid upfront and claimed it back (They did not pay the full amount) the second time they refuse to pay because I did not get Authorization, but I did and I have two separate Authorization numbers, they then say the authorization number expired and it was for the first visit, now its not valid? What is point of having a medical aid when you have to pay for all you visits and medicine?? <br>
