No response following claim submission

Submitted a claim on or about 7 January 2022. Sent a follow-up email with a completed claim form and supporting documentation on 21 February 2022. Did not receive any replies. Sent follow up emails on 16 March 2022 and 21 April 2022 none of which received a response. I have called the claims number numerous times, but no one ever answers the phone. I have called the customer care line numerous times and no one ever answers the phone. This is my last gasp attempt to get a response. Failing this I will have to reach out to the FAIS ombud as this is surely breaching the principles of treating customers fairly with which all financial institutions are mandated to comply with.
