Worst insurance experience in 55 years

I have had a car accident where my car was written off on 29 May 2021. It is a straight forward claim and they hav not yet paid . The person handling the claim is never available when I call. I get no written feedback. Now the matter is with the insure (Omnisure - OldMutual) and I had to resent all documentation and information already given to Integrisure to Omnisure. Omnisure says everything is ready and done and would have paid me on 11 August 2021. Still I havent received payment as yet. me and my wife are pensioner and are now without transport since the accident. We have to ask neighbours and friends when we have to do shopping. Even after having told this to the broker (Integrisure) and the insurer (Omnisure) Nothing is happening. I had no feedback from them at all - only one telephone call from Omnisure and one liner emails requesting information already submitted. Worst experience with car insurance ever in my 55 years of driving a car and having had it insured.
