IIBF — Invigilator not conducting my exam

I am jaiib candidate and it was my 3rd attempt...in my first attempt in 8.30 slot i reached at centre on 8.45 and exam conduct at 9.00 in my in my second attempt 11am slot starts exam at 11.10 due to some delay in password entry in my third I was late for my exam just for 5 min in 8.30 slot due to the centre is in rural area no sign board of college no people around there to help in guidance of my college centre and at 8.35 gate keepers not allow me to enter inside because observers are not answering there for my entrance inquiry when I inside at 8.40 invigilator not permitted me to take my exam...how punishing is this for me at that moment because I called one my friend her exam is yesterday told me that I am entering at 11.10 and starts her exam at 11.13 if this concession is allowed to one slot then why is happens to me ...if last exm taken on delay then 10 min delay is why for me only...i request a lot to invigilator but they are excusing for biometric closed we can't do anything...why the iibf is not seriously for their exam if others candidate allowed for another slots...and which type of biometric they are asking for when other slots have no biometric...5 min delay cost me to 6 months and are enjoying by 10 to 15 min
