Disappointed FNB client

Disappointed in FNB regarding a ***** case we have. We have 3 different ********** transactions that has happened on 3 different cards & 2 different accounts. Clearly our profile has been hacked, and transactions was done overseas with our cards. We have tried following up on this case but you get no where. This is very scary as we don't know what is going to happen next, what card they will try to make payments with again.
