Bonitas wrong network details

I have always been happy with the service. Since going under Momentum it has not been pleasant. My baby is sick (me aswell) and needed to be admitted urgently. We spent the entire day waiting for an available bed at the hospital, finally we could go. But guess what...the hospital is not on their network, even though it states on my Bonitas profile that it is. I had to leave, with my sick baby, because of a large co-payment.
