Car accident claim with Hollard insurance

I was involved in a car accident on the 30th June 2018 and till to date which more than 3 weeks there has no response regarding my car accident claim. I have to always call them back to get any feedback regarding this claim and add to this there is no urgency to even assist me. I have a car rental which is due in end of this month, July 2018, and then I am supposed to be using a public transport since definitely my car would not have been fixed by then. I regret even being part of the Hollard Insurance they just a disgrace of a business.
