Not getting anywhere with my claim

I have been struggling this past 2 weeks with the light shield for my car that was part of the claim. Every time it is a different story and I don't get feedback from the panelbeater or the insurance which I find is upacceptable. The panelbeaters have received a call that says that they can't get the shield and they haven't let me know. I had to phone them again today and then they have send me the mail. Then I phoned the repairs department and they phoned the panelbeaters and then it was promised again that they might get it. They are playing a game with a person and I am fedup with me having to phone everyone everytime because otherwise I don't know anything because they don't let a person know. I have phoned numerous time in connection with this. The assessor helped me very nicely but he is on leave and no one else can help me. Can some please just assist that we can get somewhere??
