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
