What to do when the reviewer is wrong about your paper's scope, technically inaccurate, and clearly haven't read your rebuttals
Moving on is the best approach, as @lighthouse suggests.
If you don't like the best approach and prefer to combat it, you can ask the editor for another reviewer. Politely, on a day you feel great about everything else in your life and after being absolutely showered by compliments by all of your friends has put you in the very most positive mindset, write a rebuttal identifying the review's shortcomings and suggest to the editor that some bias seems to be preventing a good review and that you ask for another independent review.
If they send it to another reviewer, your fate is then in their hands. If they refuse, well, you're back where you started: move on, submit to another journal. You express concerns about an overlapping conference submission but if your field accepts conference papers as papers then the journal article doesn't matter, and if your field does not accept conference papers as papers then the conference doesn't matter.
&quot;Bad reviews&quot; like you describe - not bad in terms of negativity but intrinsically poor - are common.
