Institute Of Banking Personnel Selection [Ibps] — withdraw and refund of fees

From many years many candidates made silly mistakes while filling ibps application forms after final submitting they have no option to edit it so they apply from new registration number new form and paid fees again if ibps don not want to provide modify application form option why dont ibps refund their fees on previous application money .if they dont provide option to candidates withdraw and refund of fees they are taking candidates money on form which is not relevent to anything
