Who gave Showmax permission?

I recently received a call from one of your agents in January 2024, expressing that they miss my subscription to Showmax. I explained that due to time constraints, I haven't been using the service. Despite this, my account was debited without my consent.Since then, I have been diligently reaching out via email to both the call center and support team, requesting a refund, but unfortunately, I haven't received any resolution, instead they sent me an email to say they are closing my case...How when I am still awaiting my money back??? I want to emphasize that I did not authorize the debit from my account.
