No response, unacceptable delays, pitiful service

Claim 23/052869 was logged on 26/06/2023. After various delays and run-arounds, I still have not received a final answer on 28/11/2023, MORE THAN 5 MONTHS later. When I phone, I can never speak to the claim handler, Yasmeen Larnie, the person answering the call can give me no details. I have sent numerous emails, with no response. What do I need to do to get an answer?????
