Money debited from my account and capitec couldn't help me in any way to reverse or find out from which company

Yesterday I got debit notification of R2000.05 from a company I don't know, I then tried to reverse the money on my app but the dispute was denied so I thought maybe it's because it's a huge amount rather I go inside the bank to the reversal and when I got there I was told they cannot reverse the money, they couldn't even tell me the company that had debited from my account and frankly I just feel the person who was assisting me didn't even show any concern or care regarding this and instead told me I should go to the police. I'm honestly considering canceling my capitec account cause I don't understand how this could happen and they can't even look into it and tell me from what company was this debit done and worse because I had not authorized any debit orders from any unknown company
