Capgemini — Complaining about not letting me give my assessment

This is to bring to your notice that today my assessment was scheduled with Capgemini company at 1 pm which was to be held on AON website but i was unable to give the exam because of your unmatched data which could not locate my assessment key and whatever not. Below if the proof kindly see to it because i don't want other students to face this situation and regret in their life. It would be better if you could coordinate among yourselves and see students don't suffer from your stupidity
