Never lie around waiting for the health "care" field to call! NEVER! Get on the phone and call your doctor immediately. Insist that you speak to the doctor and do not wait for any alleged return calls. If you must, call back repeatedly until you get through. Tell your doctor the roadblocks you are having and insist he/she do something about it for you. It's easy for the doctor to make a call to authorize what you need. Doctors get action....patients well...it's pot luck for them.

Likewater has excellent advice above.
