Budget Insurance staff not active and responsive

I had a car accident on the 28th of April 2023. I was hit from the back by a client of budget. Now....An accident report was done and documents were sent through to budget on the first week of May. Before documents got sent through, I received calls non stop to get all details on par and I thought this is the most responsive insurance company but to my surprise, after submitting all doc's I waited for the insurance to get back to me on the following step. Until I called them back after 2 weeks to find that they are missing an RC1 doc which I sent through the following day. Last Thursday, on the 8th of June I called and I was told the documents were taken through for authorisation. On Monday, the 12th my fiancee called and was told that Busisiwe Ngwenya, the one who is handling the case has not taken the documents in for authorisation. someone is not doing their job. Everytime I call in, Busisiwe is not at the office.Almost 2 months after an accident and there's no positive feedback from Budget. I just need this sorted so I can get my car back as I am using it as staff transport for my side hustle. Now I have lost income and no one is their job.
