Standard is one of, if not the worse, company in the industry Standard hasn't approved or denied my claim in over a year. They keep promising to look at it 'next week'

My husband is covered by a Standard STD/LTD non-ERISA plan. He has a very rare neuromuscular disorder and was hospitalized in intensive care, was off work for 6 weeks (waiting period) then allowed to return to work 25 hours per week, met the definition of ‘disabled own occupation’ under the plan certificate and qualified for the ‘return to work incentive’. Standard acknowledged receipt of the initial application July 31, 2018; left a message on the answering machine September 20, 2018 that the claim was approved and they were finalizing the paperwork. Now it is August 2019, over a year after the initial application the claim is neither approved, nor denied, and I have no legal recourse. But they keep promising to look at it ‘next week’.
