Fix my car

I got into an accident with their client. Their client bumped my car in the back on the 13th of November 2021. And the client took full responsibility. Filed a report, and I called budget insurance to claim. I have been waiting for some confirmation sms. I called a budget insurance and I was told to send an email with all the information that they requested. I called them again last week and I was told that I need to send them another email to another email address. I have been waiting for responses to no avail. I'm boot doesn't work due to this incident. I don't know what to do anymore
