Reactivate my account or refund my MONEY

Showmax debited my Vodacom account yesterday and sent me an email stating that I have not paid for my subscription. After calling Vodacom and shouting at the wrong people, the lady from Vodacom confirmed that Showmax did debit my account and they must of received the funds. I then contacted Showmax and they advised that the debit order bounced, which is a lie. So I then went on the pay an additional amount from my bank account and after deducting the subscription amount from my bank account, it still says there’s an error with the payment. So for one month’s subscription I have paid DOUBLE and Showmax team still wants to make it seem like I’m owing them money.
