I suspect this is a poor quality of 'predatory' journal based on the following:
1). Fees. It states that there is a fee to publish, but I can't find a clear indication of the fee on their website. Transparency and clarity are important.
2). Indexing. Because this journal is charging a fee to publish I would expect the journal to be indexed in DOAJ (and if the fee is expensive, some other important indexes such as Scopus or Web of Science). On their webpage (https://www.ijcaonline.org/indexing-) they claim to be listed in DOAJ, but I did a search in www.doaj.org and they are not listed.
Based on this information, I would not consider this journal as reputable, and nobody should be paying a fee to publish in this journal.
Let me know if you have any further questions.
