Unfair treatment

I was involved in a car accident, A Miway client bumped my car from the back in June, I then submitted a claim on the 22nd of July 2026 against their client who was at fault, I was given a claim number C***, Since then, I have submitted all the required documents for my car to be fixed, But up to date, my car hasn’t been fixed, They take too long to respond to emails, Was told to check after 3days but no response, it’s September now, I am failing to understand, what is taking them so long, I feel that I am being taken from pillar to post, Can I kindly be assisted and get clarity on when will the issue be sorted, as my rear light was affected to.
