I'm not so sure what to do in this situation. I'm a final year PhD student who submitted a manuscript for publication in a clinical journal (paediatrics) about 5 months ago. I've been tracking the online status of the manuscript and as of February 2016 it indicated "all reviews complete". Its been over 1 month now and I've tried calling, sending e-mails, no reply whatsoever. The phone keeps ringing and I've also left messages (Its based in the US-I'm in the UK). There's only one e-mail address provided on their website and I've struggled to get contact details of any of the other academics on the editorial board.
I'm just getting a little concerned by the lack of feedback or update regarding the manuscript-has anyone experienced this before? What would you do apart from keep waiting?
Edit: Just to let you all know that I heard from them a day after this post!
