Please keep calling the number + visiting the clerk of the court to check. Because of the backlog, it is hard for them to enter all the cases in the system fast. You can decide, but if I were you, I would check the automated system every day, and the clerk of the court once every week. It is important that you don't miss any of the dates, even if they are decided at short notice and without your knowledge: immigration judges are entitled to issue deportation orders if you don't show up. Many people who have missed court dates have been issued with deportation orders. Good luck.
