So I’ll tell you i was in 3 college starting January 2019 couldn’t complete the course
Got enrolled into different course in may 2019 couldn’t complete that too
sept 2019 got enrolled but couldn’t complete that
January 2020 started with this private college and it the letter it stated as 25th sept 2020 as course completion study permit rejected on 1st sept but exams were over in august 2020 ,25th sept the college told me it was the graduation day
You simply failed in three different colleges and you are in opinion that your extension refusal is unfounded??? Reasons of your refusal is you failed to maintain conditions of your study permit, that's first and second there is a gap enough to be considered as violations
you failed in Jan 2019
Enrolled another college in May 2019 ( that's over 150days gap )
then May 2019 to Sep 2019
then Sep 2019 to Jan 2020.......
As it seems you are out of status, you either apply for restoration which is unlikely they will grant that or leave Canada
