No joy from third party claim

On 23 Descember 2021 a Hollard client drove into my vehicle. After a lot of fighting I finally were able to submit my claim on 10 February. After again phoning tirelessly, an assessor was appointed on 28 February. And so I am still waiting - the phone never gets answered and via email the only response I get is : emails will be attended to on a first come first serve basis. How am I suppose to get any service out of anybody from Hollard????? Totally pathetic service, and I am expected to continue driving with my smashed vehicle! The quotes I had to submit is long overdue , not valid anymore as they were issued on 10 January. Please can a competent person react!!1
