My husbands Pension paid to girlfriend.

My customary law husband passed on July 2020. I went through what they called investigations. I was asked to bring my Lobola delegation that paid lobola because i had misplaced my lobola letter. My husband stayed with a girlfriend during our separation. The girlfriend went alone with no delegation but a **** lobola letter she wrote. All the numbers of my witnesses were not called, only 2. My neighbours, who were eager to see me back home, were not even called. I want to know how was that my husbands girlfriend was called a wife with no one but herself present and i brought my whole family and friends who were in our lives. I want to know how this investigation was concluded. A lady called Andile Ntuli, who never answered nor returned my calls when i needed an explanation. I want to know.
