Unreliable insurance assessor

I have hollard home and car insurance, on the 23rd of March 2018, I had an accident, had my licence since 1987, had car insurance for all my cars with different insurances since. For the first time in 31 years I had an accident and claimed. I’ve heard from many people that insurance will always look for any reason to get out of paying car claims. However it’s been 2months and two weeks. There was a tow truck at the scene and hollard road assist authorised a tow in to SMD in Sandton, even though I could drive my car, I said I could drive my car and insurance could come to my house to assess. I was told it’s best for them to tow as instructed as if I drive the car away insurance can refuse to pay the claim. Metro police came to the scene and said I must call Monday for case number, I called insurance from home and they said I can’t get a claim number until the case number, metro could not give me a case number until the Wednesday 28th March . I then called insurance and was told to wait for assessor’ call. Two weeks later I still have not had a call and called insurance, was again told that I must wait for assessor to call me. A month after the accident I call the insurance told the person that it’s been a month since I’m waiting, the guys in the phone was rude and abrupt, told me that I have not been waiting a month because I did not give them a case number till days later. A few days later assessor calls and says my cars has been sc****d that they will call me back. After waiting another few weeks I called SMD Sandton to enquire about getting my car back as I don’t want to pay for storage, was told by a lady there that they have arrangements with insurance that there are no accumulated storage, and they can’t just give my car back, they work through insurance. I called insurance and was told by two agents in the phone that I must wait for insurance final decision. Waited again, received a call from assessor saying the are not paying as I had an ******* tyre which could have caused my car to aqua plane, I said I’d like my car back as I can fix it, he says the having a meeting that day about the car. Gave him another week and texted he said they are not paying and I must wait. I told him that I don’t want to hear what they won’t do, I just want my car back and he said they having a meeting. I waited again an called a week later, he then told me they will have a meeting and hollard will call me back. Am still waiting, I need help, that is my car. I have had insurance all I want is my car back in the driving condition that they towed it from the scene, with all perfectly in order mechanics, and a fender smash and all premiums insurance is still taking from my bank account. I don’t want anything more or less. Desperately waiting
