They rescheduled "after receiving more RSVPs than the venue can support."
KBTX shows the original date and time as today, Wednesday morning at 9 AM (not designed for a time when they thought people could generally come).
They are apparently only going to tell the people who signed up what the new date, time, and location are. Of course, if it's at a different time, that probably means different people are available, but hopefully some of the ones being screwed over (or at least some of our local and/or state or federal representatives) will still show up to grill them about things like discontinuing service to multiple apartment complexes.
Not sure if "informational town hall" means they'll take questions though or if they think they're just going to talk.
