Unhappy client

Hi:. I have been with this company since 2011. Bought 2x Mandela coins. The broker nomore and nowhere to be found. I've been from Cape to Cairo looking for them so I can claim .the coins are fully paid. Now I need to sell and get cash for kids . It has been a struggle ever since to find them. Please have mercy bring my R52k back if coins are nomore on sale. ( each R26k). . Painful. My children are going to struggle worse if I can pass....
