Worst experince regarding a financial institution. The Second time around.

I've been ****** of over R8000 over the last 3 months, not anyone notified me that there is a major problem on my account, there simply trying to make me believe that I've entered my card detail online and thats why I'm missing 8k, even though they have issued me with 4 cards in the last 2 months!!!! I only know of 2, yet they promised me with the new card the situation would be handled, yet the problem is persisting, they will let this account run In up to R2000 to R5000 into MINUS, only to receive a threatening text saying they're going to take me to court if the amounts outstanding isn't settled immediately. They advised me that there's nothing they can do for me at this stage, not even closing the account we're my money is getting ****** out from, in fact they said it's not possible, and simply served me with yet another bank card assuring me that this is the solution after already receiving 4 with I the account holder only knowing of 2, but still they persist after 3 cancelled cards that this is the solution, meanwhile I've lost another 2000 and my account is already busy running deep into the minus mark, no one can tell me we're all my money went/or who is taking it as they see fit, they have given or sent someone a bank card with a free pass into my account as I've received a new one on Friday last week and some else also received one 2weeks ago on the 29/09/2022, with all this physical FACTS, they are still persuading themselves that's its MY FAULT, there institution (NEDBANK) has no idea what's happening to my money, not even we're it has been debited to and that they will conduct an investigation stretching over 21 days to see if they are going to reimburse my money, meanwhile the situation on my account stays as is! we're there's going no less then 15 to 20 transactions PER DAY!WHAT FOR I DONT KNOW SEEMS NO ONE AT NEDBANK (LETS GROW YOUR MONEY) CAN TEL ME..... I won't pay another cent towards that account, just because it will mystically disappear....they won't close the account and open a new one for me,even though there is a pending ***** case, on the account. Please advise, because I can't go see a lawyer as your institution has lost or given all my hard earn money away over the last 4 months it's so bad I'm lending money for you guys to throw away. Hopefully social media is of better assistance. Please assist, if possible.
