Unauthorized debit orders on my Capitec Account

Capitec Bank really needs to do something about their security, there are strange debit orders on my account and I’m being told by your consultant Carmen that there’s nothing you can do about it! I’ve never experienced such in my life. I tried reversing the amount on my app but it’d greyed out n I cannot reverse it. Then your consultant Carmen tells me that it could be because it’s outside of working hours but early in the week I was able to reverse something at 1am!!!!! I am really disappointed with this service and I am considering banking with another bank. This is disgusting service. You guys need to let us authorize debit orders instead of telling me that there’s nothing you can do about it!!!!!!!!!!
