Credit card transfer to a ********** Nedbank account

I would like to ask why FNB is not assisting me regarding the ***** that I went through in October 2020 where I purchased goods online and transferred the money to a SA Nedbank account which was supposedly the business account of the company I was buying the goods from. 2days passed and I realized no goods were coming through and when I now call the business they were no where to be found. My question here is since I was using my credit card FNB CREDIT CARD DOES NOT HAVE INSURANCE TO COVER THE AMOUNT WHEN SUCH HAPPENED TO THEIR CLIENT??? WHY DOES OTHER BANKING COMPANIES LIKE ABSA WERE ABLE TO ASSIST A CLIENT WITH A SIMILAR EXPERIENCE?
