gcx missing from portfolio

According to Computershare my MIC holding has converted to GCX. Commsec, however, are still waiting to update my details as they have not been notified. Am I the only one in this situation? From the date when GCX shares became active how long have others had to wait?

I'm just wondering whether I should be reconsidering who I do my trading through.

Would appreciate some feeback - thanks in advance.
