How to sell

I own AKE shares. I trade on line through CMC platform (originally ANZ). Now they are no longer traded in Australia I want to sell all of them but don't know how. Can anyone advise. (Have tried calling AKE office in Brisbane but getting recorded message)

I got caught out with Biota years ago. Still hold shares in my SMSF (under name of company that took them over). Every year my accountant asks me about them. Tried contacting them in US but have got no response
