Disgusting service

I am very disappointed and disgusted with the poor service that I've received from Miway after being insured with them for 7 years and not once I've put in a claim. On 11 July 2024 I was stuck in the storm deep in the water and my car couldn't start. I panicked cause I am woman alone and someone came to tow the car. The water damaged my car and it's not driving. They gave me the claim and only 3 days back I got my car and it's still not driving because the water caused electrical damages. I called them multiple times but no response. The accessor, Rowan Rose is not answering. Apparently busy. I paid access of R7400 and they gave me back a car that's not driving. Can someone please advise me what to do.
