First National Bank fail to solve **** problem

Good day my name is Mase and I have been having a very bad experience with the first national bank since the 6th of December 2024 when I realized that my account has been hacked. I decided to call the bank and was told that my account was hacked using an old card which I lost around winter. When I lost that card I went to a bank in Midrand fnb and reported that card lost. I then got a new card. On the 6 December I was told not to worry as the bank will investigate and then cancel that account. Looking at the transactions the card was used to pay many tollgates around the same time. Whoever has that card is somehow able to use the card even when my account is now at a minus. On the 6 December the account showed -3800. To my surprise on Sunday the 8th of December at night I realized the same was still going on and now my account was at -4000 plus. First thing the next day I went to Tsakane mall fnb and was given a cell phone where I spoke to someone who also promised the issue would be solved via an investigation. On the 18 of December 2024 Wednesday I went to Hendrick Verwoed fnb and tried to close my account after noticing the transactions still going on. I was helped by a gentleman there who then told me that I will not be able to close my account now that I owe the bank 3800. Today as I write this message my account has no money, and it is my salary day. The very same transactions were sent on my email by the bank where a streamline of tollgates was paid using my old card again and I managed to take out a lousy 10 000 out to my other account just so I am able to survive the next four weeks before I get my other salary in January again. I do not know what the bank experts me to do when they can't close my account so I can also be protected from the bank fees which keep on going up for something that is not even my fault. I have been with fnb for years and this has really made me hate being their customer. I regret staying with them for so many years as this is a very serious issue. What makes me angry is that it has been a whole week this has been happening, and I have not received any call from those who are investigating the case as I was promised.
