All i want is my refund

I am a new client to Vodacom but i feel tired already with their pathetic service. I took a contract in August and gave instructions that my account should be debited on the 25th of every month. I was then debited on the 1st of September and i didn't query it. Then i was not debited on the 25th of September and so as the 1st of October. I then started asking myself why am i not getting debited. On the 3rd of October i went into my bank app and made an EFT payment of the amount which was supposed to have been debited. Then reached out to vodacom and they could not give me a reason why i was not debited. I then told the consultant that they must give me an email address where i can send the proof of payment and it was provided to me. On the 4th of October my account was debited the amount which was supposed to have been debited on the 25th of September, the same amount which I manually paid the day before. How pathetic is this, now i have to do hoola hoops just to submit a request for refund.
