Dear Researcher,
Recently I am in stress as my same article published in both Journals.
1. the First journal denied publishing it without paying publication charges. Then I emailed them officially that I am going to withdraw it and submit to another journal. I got that consent indirectly from that journal.
2. Later I submitted that article to another journal and that got published after a couple of months later.
3. Recently I found that my former article also published. I emailed them saying its already published and to remove it from their publication list. But, they are not listening to me.
4. I am ethically on a problem.
