Vodacom debiting twice

I made a payment via the Vodacom app in September due to me changing my bank account. I phoned Vodacom & had asked them to change the details for the debit order, to which they rep**** that it was too close to the debit order date to change the banking details, so I made a payment via the Vodacom App.

Approaching end of October i was contacted by an agent that had told me my account is in arrears as they cannot pick up the payment made from the Vodacom app. After countless calls & being placed on hold for minutes on end i was told to email proof of payment to *** & I should expect a reply within 14 Business days. Two weeks later I have still not received a response, yet the cycle of calling & being placed on hold still continues. After that I was told to email Josias, to which i was told a week later that he does not work there anymore, then i was informed to email Thabiso Khumalo.

I have not received any feedback and as I am typing this in the hopes of getting this resolved I am on a call with Vodacom that has been continuing for 18 Min!

Worst service I have ever experienced with Vodacom.
