This question has been closed as a duplicate. I wish to suggest that the main issue has been missed when it was closed. How do I go about getting it opened? I have searched but not found the process.
Those with more than 3000 reputation points (such as you) have the Cast Close and Reopen Votes privilege. Use this to vote to reopen the post and it will be added to the review queue for other members to affirm or contravene.
If one does not have the reputation required or one feels that the review process has failed you may flag the post for moderator attention. Please be sparing in the use of this feature however as it should be used in cases that are exceptional in some way rather than as a matter of course.
If you feel strongly that neither route described above has produced a fair outcome you can post a question here on meta which has (the potential for) the eyes of the entire community on it.
