My email said, contact PP(Panel Physician) within 7 days. That probably means you've to contact and at least get the appointment for reassessment. They don't send to really care if you're out of town or what.
So better take appointment ASAP, and contact CIC ASAP to let them know that you've got such and such appointment, and that is the earliest possible you've got. Just say doctor is busy and you're helpless. Let them know that, you're doing everything ASAP, and let them know that you're still interested in pursuing the application. Otherwise they're impatience enough to assume that you're not interested.
