This is about a post-review rejection. This is one of the top journals in our field. The reviewers found our work interesting but sent a long list of controls and additional experiments to do. The editor rejected it, saying it would take a lot of time. However, most of the concerns were addressable and we appealed. The editor said he'd be happy to reconsider and we can submit, via email, a point-by-point response letter along with a new version of the manuscript incorporating all the changes.
We took the time to do so and sent everything he asked us for via email, but there's been no response in 5 weeks. There's been no acknowledgment that he received it. My advisor sent a follow-up a week ago just to make sure he received the email, but there's been no response to that either. The portal doesn't show any indication of a reconsideration. The editor doesn't have any automated response indicating he is on a vacation, and according to the journal website, he doesn't seem to have moved to another job.
I know that the situation is unusual (especially with the emailing part), but what are my options? Should I reach out to someone above him? Resubmit the manuscript on the portal? (Which is what we probably would have in the first place if he didn't explicitly instruct us to email him the files)
I have never had this long of a waiting period before we heard back from the editor about whether they are sending my submission to reviewers. (Usually takes 2-3 weeks for me). But this time I don't even have an acknowledgment of the submission in 5 weeks.
