Shocking service and delayed updates

Trying to get hold of them is shocking you stay on hold for over 40 minutes and then they pass you from pillar to post. They don't do any updates on auth numbers untill you scream and shout at them. I had an emergency c section on 2nd January 2015 and am still waiting for them to update it to pmb so the suppliers can get paid my gyne needs to be paid by Friday or I loose my discount and no matter how many times I call nothing happens I have sent 3 emails asking to be called back and no one replies to them. I have had enough of the useless service and lack of knowledge the call centre has. The hospital called and spoke to someone called Carla and she said she would update and it hasn't been done so now I am liable for all the extra costs as it was an emergency and not my fault my baby boy was in distress and had to be delivered
