What's the use of a ***** department if they won't assist...

I honestly don't see the point of having a ***** department at capitec bank... I was unaware that my card had been ****** as I make use of electronic payments instead of the card. Today when trying to pay for something I get notified that there is insufficient funds in my account. When I check the app I then only discover that there are multiple transactions where someone was withdrawing my money via cashback from a local vendor. I then proceed to call capitec ***** line to investigate they then advise me that they are unable to investigate the matter and 5he bank will not be held liable for the loss of funds...we are talking about almost R2000... It's not peanuts... I frankly don't see the purpose of having a ***** line or department of they are not willing to help and also I don't see the purpose of trusting them to keep my money safe and secure if this is their attitude when my money gets ******...
