Please help me get my car and money back

I took my car in for repairs at one of the accredited repairers by Innovation Insurance. The repairer was in my opinion not qualified to work on the car and created more damage to the car which after about a month or two or trying to get the Insurance's attention, the car was then moved to anpther repairer(the story is so long and am trying to shorten it). The long and short of it is the car has been with the new repairer for about 5/6 months now. I was told the repairs are finished but the costs far exceeds the insurance cover.

I have been paying for the car and the insurance all these months and again apying for a hired car which I was promised will be reimbursed. I told them when I took the car in it was driving. The reason it was taken in was that there was a red light that came on and was advised not to drive the car. So my beliefff is the first repairer did alot of harm to the car and I was told they will investigate right from the time the car was taken from her, to date. I told them I refuse to pay for the difference and want to be paid back my momey for the car rental.

My finances are in such a mess and I am wondering what the Insurance and the Bank MFC are thinking about what is happening to my life or should happen to my life. They are the first to take theirdebit orde but I do not have the car with me, for the past 8 months.

I do not know what a big company like Innovation and MFC can still continue when they are capable and perhaps feel proud to can dothis to a customer. Please hep me guys I am lost for words, I have been patient and all I can think of is they are bent on destroying me and my family.
