Vodacom penalized me for their mistake

I paid my vodacom account on 26 October and 27 October respectfully(on the vodacom website). On 31 October my account was still debited with the amount. So now vodacom was paid twice for my account.

To date Vodacom apparently still cannot see my payments made on 26 and 27 October. And not one single person from Vodacom has contacted me to try and sort this out. I have phoned them 3 times now and nothing has been resolved.

I reversed the one debit order so that I can actually have money to live. Now Vodacom has even charged me with non payment fees. So because their system has issues and does not pick up my manual payments(which I do every month), now I get penalized? Absolute terrible service.
