Decline Foreign T 457***

I need clarification from FNB as between 26.03.2025 and 29.04.2025 I had about 23 x -R8.00 related to decline foreign transaction t 457*** which I don’t have any idea of. Sadly this has been happening for quite sometime and i thought it was an error but I see it still continues. I need clarity as to what this decline foreign T 457 is related to and my money to be reimbursed accordingly so.
