We have submitted a paper to a peer-reviewed journal. The paper was accepted subject to revision. Reviewer A gave superficial, general comments without any specifics. Reviewer B was slightly more detailed in their comments.
I want to note that our "policy" is not to argue with reviewers but to try to understand their points and address them to the best of our extent with maximum respect and politeness. This means that our rebuttal letter pretty much starts with words of gratitude and then detailed explanations of what was added/changed to address a particular comment.
It took approximately another month of full-time work to address every single comment in full. The rebuttal letter contained detailed explanations along with excerpts from the edited paper of what was added to address the comments. My supervisor, who is an experienced professor and well-mannered gentleman with perfect command of British English made sure our ESL rebuttal letter was respectful, detailed and on point.
One month later we received another round of revisions. Reviewer B was very satisfied and approved the paper for publication. However, Reviewer A was super pissed, their second-round feedback was very chaotic with many typos and strange sentencing that we couldn't quite decipher. They wrote that we ridiculed their comments. However, again, no specifics were given. They demanded another revision without specifying what needs to be redone or paid extra attention to. Just, do another revision! Of what though?
This is not my first paper and I'm confident we did not in any way ridicule or show any neglect. However, here we are, not knowing how to deal with this petty tyrant.
I would appreciate your help! I'm getting really depressed as I'm wholeheartedly invested in this project.
