Delhi University — error in results

Address: Faridabad, Haryana, 121001

This is to bring to the notice of concerned authorities, i am a b.com (H) final year student in dyal singh college, delhi university. I re-appeared in the ge exam of 3rd semester however, in the results declared recently, i've been marked absent even though i was present and attended the examination. Furthermore, it is not just me but other students as well who re-appeared with me. Now, the college & university refuses to rectify this.
