Project 7 Rejected

Hello team, My project 7 has been rejected and it says "Plagiarism-Low". I have done all of my projects myself till now, but during the last projects, review process has become too much slow. I submitted my project atleast 5-6 days before deadline (i.e., 23rd February) and it has been reviewed on 26th, late at night. There is no mention of where the plagiarism was found, even though I did all the things myself. It doesn't seem fair from your side to keep students on wait and then reject after deadline. Even if I resubmit it now, I won't be getting any refund as the deadline has passed. Atleast state the part which has been marked as "plagiarism" by you.
