After waiting for about 5 months, I sent a humble request to the Editorial office of a Journal (having JCR Impact factor) to let me know the status of our manuscript, that according to the EVISE system was still pending for Reviewer assignment.
Next day, I received an email from the Editorial office to suggest them for potential reviewers as they had difficulties to find reviewers.
On the following day I received an email from the Editor-in-Chief that he has rejected our paper as we copied texts from other published articles. Mr. Editor-in-Chief also reminded me that, he understand that "English is not my first language", yet I should not try to copy from others.
Being surprised, I requested for the crosscheck report. In two days, I received a response from the editorial office that "certainly there is no accusation of plagiarism" with our manuscript.
Then why, Mr. Editor-in-Chief had to reject our paper based on that report and that took more than 5 months?
Later I communicated with the Elsevier and the Editorial office of the particular journal, and eventually Mr. Editor-in-Chief responded with an apology note for the "late" response, and asked me to submit the revised version, with answer/explanation of two questions. There was nothing about his wrong decision to reject our paper highlighting a baseless reason. Today, I declined to submit the revised version, as those questions from Mr. Editor-in-Chief again was simply because of his lack of understanding the paper.
I have no problem, if real review process takes longer time and eventually our paper get rejected. But it took more than five months to reject the paper based on a report which most possibly was generated immediately after the submission, and the cause shown as the rejection seem to be baseless!
Now, I am looking for some avenues where I can report such absolutely non-professional editorial decision making by the so called reputed journal having IF.
