They won't repair the car

My uncle got a car accident on 14 March 2015. <br> <br> I personally called the in the following day 15 March 2015 and reported the accident. I called them on the 17/18 March 2015 to follow up because when I called in to report on 15 March 2015, it was at night and the claims division was closed. They told me in the system the account has been cancelled.<br> <br> My Aunt followed up as well and told them my uncle is in ICU so he won't be able to speak to them. They told her the last debit was reversed. According to my Aunt's knowledge, her husband's account was up to date and paid for.<br> <br> My uncle passed away on 22 March 2015. We tried following up but they told us they are still investigating. Now the bank is following up and the car is in the yard, not repaired. We do not know what to do.
