Online Passport / ID System not working (no open slots at any given time)

Your online passport or ID service does not allow for any dates to be chosen. It seems that you do not offer that service anymore. Why don't you make customers aware before they start with the procedure and then have to go to home affairs in any case? My mother recently did hers at ABSA and had a pleasant experience. Please explain. I have repeatedly looked at the website and hoped a date would open. It says no slots are open, no matter which dates you choose, even if I try immediately the next day for the last day in the selection. I spent four hours today at Home Affairs just to take a photo and do my biometrics.
