DECLINED FOREIGN T 457896*4636

I see a lot of people complaining about the "DECLINED FOREIGN T 457896*4636" entry that you get the statements. Clearly this is a problem that has been happening for a very long time and what I do not understand is why FNB has not resolved this problem. I have received 3 of these messages during the current month and FNB keeps charging me R8.50 for each message. PLEASE FIX THIS FNB
