Need help with Disputing Debichek

Today - 04/03/2/24, R300 was paid into my Capitec account. A debichek of R260 was deducted by SSLEGCOV. I tried to dispute it from my banking app but it cannot be disputed. I went to Capitec branch at Alexandra Plaza, Gauteng. I was told that they also cannot dispute it. They said I should contact SSLEGCOV and ask them to reverse it back into my account. I got SSLEGCOV's contact details from my banking app and gave them a call but they didn't answer my calls, instead I had to hold on the line for the available consultant for almost 10 minutes then it hung up. I tried calling them 4 times and the same thing kept on occuring. R30 airtime gone for nothing. That is why I'm writing to you guys. Please, if you can, I'd like you guys to help me find a way to receive my money back into my account. What these third -party company is doing is definitely a *****ulent act. I'm extremely disappointed by Capitec bank for failing to find a way to resolve my complaint. Because their guarantee to me, as one of their loyal clients, is that my money is 100% safe with them. Their actions are not matching their words. That's false advertising. You know, marketers are perceived as liers. Today, Capitec bank has confirmed to me that their not who they're claiming to be. I trusted them with everything. But now, their no longer in my good books. Should you guys resolve my complaint, that would mean a lot to me. I desperately need that money like I need water. When it's all set and done, I'm considering to close my Capitec account. Their not willing to put any effort into finding a way or ways to resolve my issue. Which means they only care about their stomachs and not us, their most important assets. I know I'm not the only Capitec client whose complaining about this. A promise is like a debt, and Capitec bank is failing to pay...They must keep this in mind "Experience is comparable to fashion. An action that proved successful today will be impractical and unworkable tomorrow." If they continue like this, I swear they'll lose so many clients within a short space of time. Anyway, I hope you guys can help me. I've no where else to go. Your feedback would be greatly appreciated. Thank you
