Vodacom is *****ing From my Bank Account!!

I requested for a premature cancellation on my contract as i wanted to pay it up. Vodacom sent me a quotation on the 25th October 2019 with all the fees i had to pay. I made the payment (R 1143.50) on the 26th October 2019 and also emailed proof of payment to Vodacom the same day. On the 1st November 2019 Vodacom debited R463.00 from my account for no reason. I contacted Vodacom and they said that their Cancellations Department did not process the cancellation of my account. I had to call Vodacom twice a week for feedback, they had to escalate the problem 3 times to their experts because the first 2 times it was escalated nothing was done. After exactly a month of waiting Vodacom eventually paid back my money on the 1st December 2019. But this was not the end of the ***** and money *****ing from Vodacom. On the 2nd December 2019 Vodacom debited my account TWICE!!! The 1st debit was for R1537.61 and the 2nd debit order was for R463.00. On the 11th December 2019 another debit order went off for R344.77. This makes THREE DEBIT ORDERS FOR DECEMBER!!! I have made countless calls to vodacom but they refuse to give me feedback and they refuse to pay back my money!!!! How much more money does Vodacom want to ***** from my account? This is ****************!!! Phoning vadacom is not helpful at all because all they keep doing is escalating to their experts who take forever to respond or resolve the problem. I have spoken to team leaders from customer care and from the cancellations departments but none have any interest in solving my problem.
