I have lost all confidence in Capitec now I am embarassed for all the good things I said about them

I am so dissapointed with capitec, I am even embarassed because I always stood by capitec when colleagues said bad things about this bank. I got so excited about live better bank better products, got some cash back I screamed for all my close colleagues to register for live better. I never anticipated being a victim at Capitec bank. I wake up this morning to be met by a notification of some online subscription that took over R800 from my credit card account. I have always blamed clients for things like this thinking it is their fault for clicking on strange websites and insering their bank details thinking I am not stupid enough to do this. I have no reason to subscribe to "CRUNCHYROLL". I google this crunchyroll and I find that its an online streaming service for cartoons. There is absolutely no way that I would even be intrested in clicking to some cartoon website. Who authorised this "Purchase" because that is what it says, I did not authorise it. Why is it going off as R848 when my limit is R0.00 for online, R200 for swiping, R0.00 for withdrawal. What kind of purchase is this? If it is a subscription is capitec not supposed to send me a message so I can authenticate it to avoid theft and *****? I am so confused and heartbroken over this. R800 is a lot of money for someone like me. I am even discauraged to go and lodge a complain from what I see on these reviews, there is no hope that I will get my money back. So confused because I love Capitec, now I do not know which bank to go to.
