Khulasizwe shares = no return, just a donation

I bought shares in 2019, there's been no dividend payout ever since.. and I am told I can't sell them. This feels like a ****; what good are these shares to me? It looks like I just donated my money to Barloworld. This looks more and more like unjustified enrichment on Barloworld's side. My money is gone but there's nothing in it for me.
