Fed up with FNB and their dishonesty

FNB does it again! a Week later since R8000 was ****** from my account from Zambia... Cancelled my card and received a replacement card. Yesterday FNB refunded my money, I immediately contacted the bank to confirm that the ***** case has been finalized. The lady assured me that eveything is fine now and they will still be in contact as to how this happend. She did tell me that they might try and deduct the money again, I told her that it shouldn't happen because I have a new card with new details so how will it be possible for them to take money out of my account if the details is no longer the same?? Never the less, I didn't really got an answer on that. However she said that I should not panic as FNB will refund me again. So this morning the money was yet again debited from my account. I phoned the FNB ***** department to ask them what I should do on my side to let them know that this happend again. She (Rebecca) advised that I need to speak to their investigation team - like how am I suppose to know who that is??? I got really upset as she said the money could have been banked at the unknown merchant who keeps *****ing my money. As soon as I told her that they need to help me, because they are the bank and I'm getting quite fed up of FNB, she dropped the call. After having to hold for 7min before the ***** department can assist you. FNB once this **** is done - my account will be closed in seconds. You are the most pathetic and most rude bank I have ever came accross. Shocking to see how many people are unhappy with your service and yet you keep on failing to provide better service and solutions to your customers.
