請問pjiang老師，I485 pending,誤了ASC Appointment of biometrics兩天應采取什麽補救

pjiang老師，我的I485 pending, 接到ASC Appointment Notice到local Application Support Center "have biometrics taken"。但我全家外出，等看到這通知，已經晚了兩天。我準備明天趕到local ASC看能否補做一下。

通知上說"If you fail to appear as scheduled, your application will be considered abandoned"。象我這種情況，I485 application會否真的abandoned？我還應該采取什麽補救措施？謝謝！
