Claim case close without validating the documents.

I have been involved in a car accident n the 25 of June 2022. I reported the accident to Tuesday 28 June 2022, I opened a case at Linden policy station on 25 June 2022.

I sent all the documents they required, no reply or any form of communication. When I call the loss adjusting person he told me that the case is closed.

My question is how can a claim be closed without validating the documents?

I was only given one person to be in contact with, when I send emails he does not respond and is had to even escalate the matter as that's the only person I can contact.
