bad Service and attitude

My husband was stabbed and he went for a CT scan. According to the medical aid i need to make a co-payment of R2500, a woman called Jesinta told me not to pay first and that she will talk to the medical aid be because he was stabbed and that the scheme might pay. She then came back to me after two day that the medical aid will pay the money i do not have to worry about that anymore. a month down the line i am being called by the hospital to pay the R2500 and i have paid R1000 because i thought it was for something else. one do you tell people not to worry they you worry them and worst of all she is not apologizing or taking responsibility but she is known telling me that she is busy to follow up on her mistakes. Its people like her that do not deserve to employed. i will never ever use this hospital again because of the bad service.
