Application of ID document South Africa

I am in need of assistance in obtaining my South African Identity Document and would like to get some information and analysis from a professional's perspective. Let me explain my full story below: I was born in Rosepark hospital in Bloemfontein on 31 January 1998 (SA ID no 9801315127086). My mother is a South African born citizen (SA ID no. 7505120065082) and my father is a Namibian born citizen. At the age of 3 months, myself along with my parents moved to Namibia. I resided in Namibia for 25 years and both my parents still reside there. My father is estranged from my family (even though my parents are legally still married). I decided to move back to South Africa recently and I have been trying to apply and finalise my South African ID with no success. I have gone through 3 separate occasions of filling out all necessary forms, providing certified copies of my South African birth certificate, Certified copies of both my parents South African and namibian ID's, marriage certificates and police affidavits from both parents that they are my biological parents and to certify that I was born in South Africa and a letter from the department of home affairs in Namibia asking DHA south africa to assist me in obtaining an ID (Along with my unabridged South african birth certificate) . Every occasion has resulted in the same answer. One of my parents needs to be present to apply for a South African ID. This is unfortunately not a possibility as my father is estranged from my family(have no idea of his whereabouts and have not spoken to him in over 13 months) and my mother has been in South Africa as well and I was denied verbally as my mother does not own a south african ID anymore as it was taken when she applied for Namibian citizenship. I have also gone through the online process of confirmation of citizenship and I have been confirmed as a South african citizen. Every single aspect that verifies me as a citizen has been approved I just cannot get my ID thanks to my parents not being present and/or not having a South african ID. I am at my wits end and I do not know what to do anymore. I beg for some assistance and I am willing to contribute a substantial amount of funds to get this sorted.
