Finally, our app was approved last Friday. I hope you will get good news soon. From my perspective, you shouldn't send an expedited request after rejections. This is Apple's message from the expedited request section:
"If your submission is rejected during this review, you don't need to request another expedited review when you resubmit. Your resubmission will be automatically returned to the expedited queue."
