Income Protection payout time

Hi, I am a HSE employee with over 30 years service. I had a medical episode in January 2024 which renders me unable to return to work for now.. I am not sure if I will ever be able to return. I have a union-backed salary protection policy since 2005 . I have put in a claim in March but am still waiting for any payout. If I hear nothing in the next week, it will be the end of November 2024 at the earliest . I was told 13 weeks before payment which was fine, but it is now well past double that time. Anyone else have similar experience or advice?
