Unresolved and continues ***** at first National Bank SA

I'm stressing and depressing with poor response from fnb ***** department, I got ****** my bag and lost all my belongings including my fnb cheque and credit card. I blocked the cards and app**** for new cards. I received new cards. Now I'm experiencing some transactions that I don't know of on both credit and cheque card when report these to ***** all I get is they are investigating it and my money will be reversed to my accounts that is not happening. I asked as how come my account is being attacked like these while I'm having a new cards their response was only investigators at ***** department can tell, I tried calling that department on *** for days I hold for almost an hour using my airtime. So frustrated with no help I went to the fnb branch to speak to the manager seeking for help because my profile is being damaged, beautiful lady at the branch check for me as from which card are those transactions and surprisingly they are from my old blocked cards, is showing on the system that my cards are blocked but in use how possible . Now I want to close the accounts and move on with my life but now how am I gonna get my money. I'm so fed up and trained because this thing it's happening every day and my accounts are now all on negative overdraft.
