Horrifying experience at Nedbank

On the 29th October, it was on Saturday, i was sitting at home having breakfast when my phone beeped, an amount of 424.99 showed my card had just been used. i rushed to the bank the same day to tell them i did not know this transaction. The response i got from them was that it does not reflect on their system even if the money has come off my account, there is nothing they can do to help me. i was told to come back in a day or two. since i am working i could not go the bank then, i went this past Saturday the 4th, little did i know that on the very same day 8 more transactions were done on my card, totalling 697.93 plus the 424.99, total amount , 1122.92!!! i only got one notification!!!!!!!! no notifications were sent to the my phone except the one for 424.99. Now Nedbank tells me they cannot help me, the people at enquiries are treating this like any normal **** by telling me that they hear more horrifying stories everyday about people being ****med. Every month i have to reverse unauthorized debit orders and i get charged for this by the bank. i know that this is happening to a lot of people out there and there is nothing they can do about it. The banks are supposed to secure our money but this is not the case, they just shrug their shoulders. i am writing this out of pure frustration, i feel helpless, this is my money, no matter how much... i work hard for it. No one has a right to do what they are doing to our accounts.
