VERY BAD SERVICE

My dad is covered by oneplan health insurance. He collapsed today and we took him to the hospital. The doctor informed us that they need to hospitalise him to do more tests as they did ECG scan and on the scan said abnormal ECG. The hospital contacted oneplan for an authorization and they said they cannot authorize this as my dad is not in the red zone. They classified my dad in the yellow zone. We feel that this is much more serious. Each month my dad gets debited for a service he can't really use.
