mitigating circumstances

Hi sir, during my AFM exam, which was centre based CBE, the keyboard and the mouse provided in the exam were not properly working and if it was not the case, i would have been able to complete the paper betterly than now. will this issue be eligible for mitigating circumstances.. i read the articles on mitigating ciorcumstances and found there is a seperate centre complaint section. but im still not sure where to register this issue and whether im eligible to apply for mitigating circumstances. it would be great if u can provide some insights on this issue thankyou
