Folks, I kinda need some advice from y'all
So I'm currently an undegrad without much experience in publishing scientific papers. Due to the pressure of many of my teachers and peers, I felt the need to get something published so I contacted an open access journal which belongs to the Herald Scholarly Open Access group to publish a review paper I initally made for a class.
I initially submitted my paper in good faith thinking that it was a legit journal as everything seemed to be in order at first, but after I submitted my paper I started seeing some alarming red flags all over the place. The most alarming one was that the peer-review process lasted only a week and resulted in no major changes to the article other than changing the citation style. They are now asking me to pay a huge sum of money which I cannot and do not want to pay considering that I'm possibly dealing with a predatory journal. I even tried asking for retraction of my article but they are asking me for a withdrawal fee.
So, has anybody been in a similar situation? If so, could you give me some advice into how to proceed? To be honest, I don't care that much if they go ahead and publish my article anyways (which I've heard some journals do), I just don't want to deal with a journal that could be a scam.
