GEPF not finalising funeral claim

As the executor for my mother-in-law's estate, Ive submitted her claim to GEPF in September 2022 - the experience has been torturous. Suffice to say that it has not been finalised yet and I am calling almost every week to find out what the progress is. Over the months, to date (April 2023) I have made 18 calls just to be told I should follow up in a week's time.
