Miway insurance my biggest mistake

About a month ago miway approved my claim for damages on my car they came and pickup the car after 2months they phone me they can't fix the car because there is something wrong with the gearbox keep in mind I paid R110000 for the car the gearbox place wants R112000 to fix the gearbox this so I said to miway rather bring my car home I'm gonna fix the gearbox myself but they drop my car with a engin that is holding on to ropes they gearbox parts is lying in the boot the the hole car is full off engine parts and covers full off oil I phone them they said they gonna come back to me but it's 2days later got 3 cars insured with them but I'm done
