Road Accident Fund is so disappointing and care less about their job playing with peoples feelings

I phoned Road Accident Fund regarding my mother's claim who passed away while she was waiting her money to be paid to her. My mother was involved in a car accident in December 2008 and she claimed and waited unfortunately she passed way in August 2011 while she was waiting for her money. I then decided this year (2019) to do a follow up on her claim, when I phoned on the 9th of April 2019 the lady I spoke with asked for my mother's name, surname and ID no. she then told me that she can see my mothers claim on the system but before she assist me further I must go to court and ask for the letter of authority. I then went to court, at court they said before they issue this letter Road Accident Fund must give me a statement that is disclosing the funds that are to be paid to my mother I phoned at Road Accident Fund and told them what the court said they said they want that in writing and I must email it to their email address I went back to court to get this letter and I emailed it. I phoned Road Accident Fund they said I must wait for 72 hour until they receive my email, after 72 hours I phoned the guy I spoke to told me that there is no claim for my mother on the system I asked him how come then he told me there is only one claim for paramedics who claimed for treating my mother on that day of the accident but there's nothing other than that. I asked him how come the lady told me there is my mothers claim, he said she made a mistake! She made a mistake at who's expense? She wasted my time, energy, money and made me hope for something that is not the way I think it was. I really want justice in this and I am so disappointed that this lady doesn't know her job and doesn't even can for that matter , how can Road Accident Fund play me like that..I am so sad and disappointed
