My car's parts missing under the care of Idirect insurance after they declined my claim

So after Idirect insurance refused to pay my claim, now when they bring back the car the parts are missing, my car cannot lock like it used to. Arrogant and heartless people, my son's safety is less important to them they looking at getting the bonuses after not paying my claim. As black people we are victims in these incidents, I was warned only after the incident that Absa don't pay right offs, I have been paying comprehensive cover thinking one day when I need help I will be helped and they come here and tell me my son was supposed to stop on N14 in the early hours, so its okay if anything could happen to his life so that they don't pay the claim.
