We've been told that hiring a home caregiver for my father with dementia will only be covered if the caregiver is certified in dementia care. What does this entail?

My Mother is insured by the facility in which she stays. She has been paying $1,000 per month for 15 years and she should be insured but the facility has refused to honor the policy. I go there every day for as long as I can to assist my Mother. I am not permitted to stay overnight. They charge $25.00 per hour which would run $70,000 for an 8 hour shift per year. We used the services for 3 months when Mother was at great risk of falling - paying out of pocket. Mother should have round the clock care. How do we file a claim with the facility housing my Mother? Mother has been scammed and is being treated poorly. I am being retaliated against for asking questions about why they do not provide the Nurses Aids 24 x 7 and other matter too outrageous to state as it would take away from trying to get her the 24 x 7 care that she needs. I love my Mother and want to do right by her. Where do I go?
