RE:zena.rtAUSTIN48
You can purchase ZENA.RT on the open market and when they are in your account (hopefully sooner than later) you then call the bank (investment line) and they will convert them for you.
But time is running down. Try to complete this process by tomorrow or Monday 25th November for the latest.
After Monday forget it because there would be a stampede and it will be fulfilled on a "best effort" basis
