I'm not happy with Capitec bank

2019 I banked with Capitec in October I had R200 deducted from my bank account from people I don't know tried to revert the money I couldnt, I then went to the branch to find out how can I have this money reverted and who are these people, I was advised that it an unknown source so I told the consulted that how can my money not be safe as you are a bank so you will let unknown sources take people's money and you don't do anything about it, then they say we will investigate they gave a number to contact these people myself and tell them to stop the debit, so I said I need to do that why can't you do that because I'm not aware of these people when you say you are going to investigate how? Coz it seems as if I'll be investigated for you now. I was then told we have a special team that is dealing with ******** who will put a stop to this. I waited to be called back by the bank nobody did from the ***** team. November same thing happened R200 was taken again, I went there to change the card because they can't do anything about it I was told I can't because I have a loan with this card, I said how can you say you can't because you can't do anything about money that has been going out of my card, they send another ticket for investigation I was assured that it will be sorted but it wasnt, again December same thing happened I was told another lie up until I finished their loan and changed bank. 2020 the card was still active I went there to change the account I was told I can't with the old ID I can carry on and use this one, I explain to the consulted reason why I want to change it he said no they won't take your money anymore it been a year and it shows that they haven't tried so they wont, I took his advice for it. I deposited R500 from the card in September or October I ain't sure got a notification R200 debited I checked it was the same people they couldn't do anything about it. I had faith in Capitec with my money but they couldn't help me at all, it seems as if it was an inside job because ever since nobody has been in contact with me in regards to my money. It R800 in total that I have lost from Capitec. Hello Peter please help me I need my money back I've been silent for a long time.
