Dear Hari, am sure you are aware of the fact that your official Test Report Form will be released to you 13 days after the test unless otherwise specified in the information provided by your test centre. The online preview cannot be used as official confirmation of your IELTS result. So I would say, keep an optimistic eye on the results. This is beyond your jurisdiction now as you have already given your exam. The results are unfortunately not in your hands. I know that this involves a high amount of fees. But breaking your head about something that is beyond your hands' reach can only cause you stress and worry.
