VIT University — Not being able to give exam

I had viteee at time 11:30am to 1:00pm so I logined to give the exam, but the codetantra didn't seem to work, somehow I managed to login the site much before 11:30 am. I connected to the main system as well as third eye. But still I wasn't able to give the exam and then I contacted the proctor.The proctor told me to wait for a while, then he told to reload the exam page.when I did that my test status seemed to be expired.i contacted the proctor again he said he blocked me eventhough I was connected to third eye.when I later said that I couldn't log in, proctor told me I was late for exam. At last I couldn't give the exam
