Hello po. I did not inform DHA na I won't make it sa 28 days deadline. Lodged my visa on Feb 7, submitted my medical on March 12. Seems like they know na mahirap talagang makakuha ng schedule.
If you really wish to inform them, in your Immi account, update details, baka pwede mo isingit yung case mo regarding medical.
Ito yung explanation about update details:
Update details allows you to provide the department with new information or to change information in relation to your application. This includes the following forms:
Appointment or withdrawal of an authorised recipient (including migration agent)
Change of address details
Change of email address
Change of passport details
Notification of changes in circumstances
Notification of incorrect answer(s)
Request to cancel a temporary resident visa.
Di ko sure, pero baka makatulong.
