Disgusted at the lack of urgency by the UIF

I was retrenched on the 31/03/2019 and app**** to the UIF for my benefits the week after. At first the service was good because I received communication from the UIF within 14 days. I received my first payment a month after but the whole payment was held back by the UIF because according to them it is an over-payment because I withdrew from the UIF while I was employed. I disputed this and investigated the matter myself and even provided proof to show that there findings were incorrect. It is November 2019 and I have had no positive feedback from the UIF. I drove to Pretoria from the westrand to try and resolve the matter just to find out that the lady who apparently is dealing with my query is and has been on study leave for sometime already. I just don't understand the fact that there is no one else to continue with my query while she is not there and it is so frustrating because you are sent from pillar to post because no one is willing to take responsibility...I am pleading to someone out there to assist me in getting this matter resolved. I have a handicapped son at home I need to care for and have not earned a salary for the past seven(7) months. I still do not have any answers from the UIF. I sent an email to the UIF complaints department two(2) months ago but I have not received any reply.
