The host actually did follow up in person and tried to escalate. There wasn't another doctor's office to send them to, because the tests were explicitly called by a specific doctor and there would need to be authorization to transfer the tests... authorization from the doctor who wasn't responsive. Like I said, this was extremely distressing to hear about the host needing to apparently decide that this was their fault and the resultant distress the host was experiencing when after two weeks and many attempts from many angles, they were unsuccessful, and according to the advice they had no one to blame but themselves.
