If you wrote (several times) to them to withdrawn your article before they publish it you have not to care about them. If they published it them you asked them to withdraw your article you have to contact them via Email or try via a phone call and tell them that your decision is not to publish it any more with them since their Journal does not have DOI. Furthermore, you have to justify for them why you are decided to withdraw the paper. I.e., the paper will not count or considered for your promotion.....etc.... Best wishes.

Dear Sara Napolitano ,

Indeed, though they look misleadingly professional they are not. “Austing Publishing Group” is mentioned in the Beall’s list (https://beallslist.net/) and numerous disturbing things are associated to them: http://flakyj.blogspot.com/2017/08/austin-publishing-group.html Furthermore:

-After all those years no serious indexing (https://www.austinpublishinggroup.com/indexing.html ), as a matter of fact DRJI is a well-known example of a misleading metrics (https://beallslist.net/misleading-metrics/ )

-Looking at the specific journal, they prominently mention impact factor a 2.1 (https://www.austinpublishinggroup.com/clinical-case-reports/) which is to say the least misleading because they are not indexed in Clarivate’s SCIE (which can be checked here https://mjl.clarivate.com/home)

-They struggle to get enough submissions and mostly likely desperately need content (https://www.scilit.net/journal/761969)

In other words, this ‘publisher’ is using questionable practices and unlikely will respond to your request to withdraw/remove your paper. It would be a good thing if the Tumori journal (https://journals.sagepub.com/home/tmj) is willing to publish the paper (despite the fact that they are fully aware of the problem). Though this would be justified it is unfortunate that the ’law’ more or less protects these types of fraudsters in terms of copyright etc. and seems powerless to punish those who do not follow ‘the rules’. In general, this is the current status: “If I publish an article in a predatory journal, can I republish it elsewhere? Sadly, dual publication is a breach of publication ethics whether the original article is published in a predatory journal or a legitimate one. The best course of action is to build on the original article with further research so that it is substantially different from the original and publish the subsequent paper in a legitimate journal.” (https://blog.cabells.com/tag/predatory-journals/page/2/).

Best regards.

Dear Sara,

If you do not pay the fee, they will not publish it, and you are on the safe side. But always keep all the emails you wrote and the replies as evidence.
