When I went to buy in to BSP a month or so ago, I couldn't purchase the shares, it said the ASX Code did not exist, even though I was able to get a quote on it.
I rang ANZ Margin Lending and they said that since the company floated, not one single share had been purchased by an ANZ ML customer so it wasn't in their database, and they had to add the stock in for me.
True story.
