take your gckey back from your agent... and do as suggested by @row.one because you waited for 6 months.. it is not your mistake...it is IRCC's mistake.
contact your college and say i want extension to submit AIP and if possible give the screenshot of your application status from immigration portal....chances are they will give the extension.
If this was the case than why didn't they gave me full approval.....they are speaking some different thing and doing different...they tweeted some days back that they will give full approvel to complete applications
i have told the college for date extension....they told me to give screenshot of application status plus they will take decision on 17 august after the meeting.
