Irregularities in recruitment test

The Agrani Bank has cancelled its recruitment test for the posts of Senior Officer, held on 31st May, over question paper leakage. As a candidate for the post, I was worried about the fairness of the recruitment process since I observed following aberrations from the norm:
-- Some examinees were using mobile phones in the examination hall although it was strictly prohibited.
--The teacher on guard was absent from the hall in the last fifteen minutes giving the examinees a chance to resort to unfair means.
I hope the bank authorities will take corrective measures for the sake of fair recruitment.
