Prudential is basically waiting for my boyfriend to die

My boyfriend is permanently disabled thanks to medical malpractice. He applied for Prudential long term disability and was denied. He appealed, submitting 500 pages of medical records including X-rays, MRIs, etc., two independent medical exam reports, and a list of 18 doctors. Prudential has surpassed the 45 days to respond and has sent more forms to be filled out. Are they ever going to pay him? He is housebound, cannot work per doctor’s orders, and has no income. He worked for the same employer for 18 years and has an exemplary work record. Unfortunately, that employer is also a sovereign nation, so he can’t get the records for worker’s compensation either. Prudential is basically waiting for him to die.
