Hi, you should try to request them for an expedited appointment again. I just got an email saying that my request for an expedited visa appointment has been approved by Abu Dhabi consulate. So yesterday, I rescheduled my appointment in Abu Dhabi by choosing 'Missed my appointment' option. I booked a regular appointment in Abu Dhabi for 13th October. After then, I decided to place a request for expedited appointment.
They have given me a slot on 24th August. I don't know if it'll work but fingers crossed!
