Our money is not safe in Capitec bank

Our money in Capitec is not safe at all, we just banking because of less cost but for not safety . In 2 October 2019 R950 was withdrawal from my account without using my card. When I lodge a complaint they told me that this is not a ***** because someone use my card @6 in the morning. I ask them the footage of the camera as every ATM has a camera they refused. For me I suspect that is internal staff that they stole my money. Why they don't want to show me a footage. They told me that they can't refund my money I have to change my account. Is that how they solve our problem.
