Failure to investigate ****** property

I was involved in a vehicle accident. The vehicle was written off and i chose the buy back option.<br> When the vehicle was inspected, it was stripped of some parts so as to attain the extent of the damage. When I inquired about the way the st********** items were stored I was told not to worry and it was noted. When I went to pickup the vehicle I noticed that there were some items missing from the vehicle and I informed the people working at the yard and they said they do not know anything. I called the insurance and I was told to check on the tick list of the towing truck what was brought in with the vehicle. after that i noticed that more than 1 item was missing and i again called and explained, the lady promised to get back to me but nobody did so. I called numerous times over a space of a month and I was told a senior manager would be in contact with me but till yesterday nobody had contacted me, they tried to contact me at around 5pm yesterday, and got my mother and the phone got cut off. Now they say I'm only reporting the issue now meanwhile I have been calling them @least twice a week over the past month. The 1 major missing item is worth +/-R6000 as quoted by their assessor.
