Every hospital has a PALS service. The Patient Advice and Liaison Service (PALS) offers confidential advice, support and information on health-related matters. They provide a point of contact for patients, their families and their carers. Especially if not satisfied with the service you are receiving. They can often cut through barriers to getting the information you want.
