I would call every other day during the week. They are open until 8:30 pm eastern. If you get someone less helpful try again later in the day. Some at GIS are better than others. I finally got the confirmation from GIS that my BGC was complete and I called again the day after to make sure it was sent to JetBlue. Keep on them, politely. Now I am just waiting on jetBlue. Hope to hear something, anything soon.
