Authorized ornot authorized?

I sent in authorization forms for my husband to be admitted to hospital. I got a nice automated reply stating they will get back to me witin 24 hours. After 24 hours nothing, so I submitted the authorization again. Yesterday I received a Preauthorisation letter to authorise the procedure. Today they sent me another letter stating that it is not authorised. This after we already gave the authorization number tp the doctor and booked a bed at the hospital. I tried phoning the number but it is out of service. Honestly how is this even possible.
