Liberty life insurance is the worst

My husband has a policy with liberty life insurance, we have submitted a claim for dread disease in February 2022, since then we've submitted every possible requirement requested by them from my husband's medical transactions from his medical aid to hospital records, and every time we think we getting somewhere with this claim they find a way to request something else, each time a request is made we are told they have a turn around time of 10 working days. After numerous phone calls with our advisor and then calling them directly I get told it's getting assessed then I was told it's with the claims department, finally I'm being told it's gone back to the assessors for further assessment. During this time my husband's health has declined further and is now 100% dependent on oxygen therapy and the stress of not getting any answers from liberty isn't helping his condition. Surely 7 months is sufficient time to assess a claim unless they're trying to find some loophole to get out of paying the claim.
