Iwyze insurance refuse to settle my car

case no. *** base on the following reasons -On 5 April 2019 I was involved in accident where the car was damaged at front and rear side -the car was taken to unlimited penalbeating in rustenburg and done quality check at bmw in rustenburg - a month later the started making noise from the front when driving only -after that I booked the car at rustenburg for service but they didn’t tell me if there’s anything wrong with the car -on September the car was making too much noise from the front -I took the car to club motor in Pretoria for brake pads change and for them to check what’s causing the noise from the front -I was told that the car was involved in accident before and it was not fixed according to BMW standards -also the car is leaking oil from the gearbox -the car was signed back to me and advised to take it back to BMW in rustenburg for quality check again -I wasn’t advised not to drive the car after the inspection was done,simply means that the car was still drivable -I booked the car at rustenburg BMW two(2) times but the service was not confirmed with me -on 30 September 2019 the car burned down while driving -The fire was coming from the drivers side in the bonnet -on the photos of previous accident it shows that the car was leaking something from bottom -from the feedback I got from the assessor,he said that the radiator was leaking but the quote I have from unlimited penalbeating doesn’t show that radiator was fixed either -The car was damaged from previous accident but it wasn’t fixed correctly and No proper quality check was done on the car according to the information I have Right now the insurance doesn’t want to pay cuz they say i did give the car attention
