Two weeks now and my request for details of my current Oncology Benefits still not fully finalised

Two weeks now and my request for details of my current Oncology Benefits still not fully finalised. First request was on 13 March and was followed up by a chaser mail. Eventual response was: "please note that we cannot determine the nature of your query." What could be simpler than my original request: "Please provide me with my authorisation #’s for ‘23/24. I never received authorisation letters for this period but also had no need of them until now" WHICH WAS SENT WITH MY MEMBERSHIP #, TO ***. On 19th I mailed back and enclosed copies of the two authorisations received in '22 for your guidance. This resulted in receipt of a mail on 22nd enclosing authorisation letter BUT FOR ONLY ONE OF THE SUBJECT CONDITIONS. I followed up same day and am still waiting for the second authorisation letter. I don't pay you 60K plus per annum to get this kind of service and I also expect that as a member of the principal fund (your own fund/product in fact) that you administer among some ten/twelve/or more, that my requests should be dumped upon receipt into you overall work queue for attention (and hopefully resolution...but not in this case yet) until your work queue processors eventually get around to them – as appears to be your standard practice. Please expedite (asking for expedite for the second time now)
