Hello everyone

Every now and then there are a promotion on social media such as facebook or instagram about this publication assistance on scopus indexed journal, recently one of this have contacted me through my mail, the company called itself "Publisher Gate", i have talk to them and they provide me with some of their past client testimonies, but i still in doubt on using their services. Maybe some of you have encountered similar services company, or maybe have used this Publisher Gate assistance, is it safe to use this, are they legit and not just some scams..

Thank you
