GEPF - Poor performance on refund of funeral cost

My father passed on 15 August 2024. I paid for all funeral expenses. I filled out all required forms, all required documentation copied and certified. I emailed the email address listed on the instruction form. For 3 weeks I have been emailing the same email address as well as national and local email addresses from the website. I have had no acknowledgement of receipt, I have phoned repeatedly every day, getting either a message that there are systems issues or getting an engaged tone. It is disgusting that at a time of loss and sorrow, I have to deal with this absolute lack of service provision.
