Save Labiba from Debt Collectors

My scholarship was rescinded for Fall 2018, Spring 2019, and Fall 2019 of college because I didn't complete enough credits for those 2 academic years. 
I wasn't able to complete enough credits in the Fall19/Sp20 academic year  because in spring 2020 I took a break from school to work on the Marcela Mitaynes campaign.

Now, I have debt collectors calling me and I am afraid this will affect my "credit" and ability to get housing in the future. I also can't register for classes until I pay off the full balance. 

Would appreciate any and all help!
