Unclaimed benift runaround

I have been assisting my father to claim his unclaimed benefit from your organisation since July 2014 and to date the money has not been paid out. I keep being sent from pillar to post about the documents I need to submit and nothing ever gets done then I have to redo the whole process and resubmit the documents all over again and still nothing happens. My father is based in the EC and im in WC and he is terminally ill and getting all these documents has been a mission due to his ill health. This has even caused emotional strain between us as he is now starting to think that the money has been paid to me and I used it for my own benefit and you can imagine the pain this is causing me as I have to defend myself to the family because liberty is giving me the run around. Secondly my father is on a state pension and he specifically opened a bank account for the purposes of this money and its costing him R50 every month to keep that account open that he doesn't use for a whole year. If u only get 1300 pm and you must buy food and medication R50 is a lot of money. As I said he has a terminal illness and his money could make his life better even if its for a couple of mnth.please help
