Poor services and no communication

Is been a month and half since I got an accident and am insured with miway, miway took three weeks before they could assess my car. They called me to let me know that my car is repairable ,so two weeks ago I followed up with the panel beaters they said they’re still waiting for the parts. This morning when I call the panel beaters they say the car is written off. I am paying this car the full amount and the insurance and the hired car as I have to travel to work. I am paying for a car that I don’t know if is still existing or no more. I am so disappointed angry with miway with their poor service.
