Missing items while the car is in their storage

Pmd rejected my claim then they returned my car with stollen parts, reported to them and at first they denied that they were any parts missing and the guys from their storage they even cut the whole wiring from the car then provided proof to them that items were there when they took the car then after having proof they accepted the responsibility of loss and said they gonna pay me for the missing items. Ive been communicating with Zolani Ngwenya from the complaint department and he gave me the worst service ever, his attitude is filthy stinking, one day he says something then the next day he’s changing his statement and now hes saying they gonna pay for some of the items not all of them
