3+ month delay in reviewing the revision of paper, Editor doesnt even answer the email

I've submitted a paper in an ISI journal, i.e. in Taylor and Francis. The first submission date of the manuscript was 30-may-2014. We received the first revision result on 27-July-2014. Hopefully, the result of reviewing our paper was optimistic as the paper status was accept with change; we had only some minor comments. We submitted the answer of revision on 15 Aug. They didn’t reply our revision yet. So,I've sent an e-mail to the Editor in chief. But he didn't even reply our email. The handling editor identity is not available for us. What is your proposal in this case?
