Elite Mobile - Fraud and theft, illegal and unauthorised debit order by vodacom and elite mobile

On 26 May 2023 I received an unsolicited call from Vodacom to try and sell me an upgrade on my existing contract. As it later turns out this was not Vodacom phoning me, but some third party called Elite Mobile. I made it very clear to them in the call that I do not agree to anything that will in any way cost me anything more than my existing contract with Vodacom entails. Despite this, the person who phoned me - by the name of ** - ignored this, went ahead and upgraded my Vodacom account (illegally and without my consent, actually against my explicit refusal). This is fraud. This only came to my attention a month later when I received a SMS from Vodacom to indicate what my next debit order deduction will be, which was more than twice it should have been. I immediately contacted Vodacom, who then informed me that the fraudulent transaction was committed by Elite Mobile. Vodacom opened a case (dispute no **), but I never heard from them again. I also immediately contacted Elite Mobile (Vodacom supplied me with the number) and have since then (for the past month) had exhaustive conversation (telephonically and written) with Elite Mobile. Since the conversation on which the fraud was based was recorded, Elite Mobile (one ** was attending to this matter) listened to the recording and admitted that they acted wrongfully in deducting money from me without my consent (i.e. fraud and theft) and that they misled me. I asked them for the recording, which they refuse to provide me. On 3 July 2023 a fraudulent debit order indeed went off against my bank account, despite Elite Mobile indicating that they had reversed the transaction. This is theft. They then also admitted that when they tried to reverse the transaction on my Vodacom account to what it was before they committed the fraud and theft, they were unable to do so, because Vodacom fees increased in the meantime. Thus they are continuing with fraudulent actions on my account. They eventually suggested that they remedy this by refunding me for the money they stole and for the increase on my account for the duration of the remaining contract. It took them a long time to get the figures right. They are now, however, refusing to sign the letter of compensation (though they expect me to do so!) and they are refusing to provide me with evidence (from Vodacom, with whom I have a contract) of the state of my account, invoices and debit orders. I cannot agree to anything until they provide me with the evidence/proof to which I am entitled as a paying customer and until they sign the letter of compensation. The person at Elite Mobile wo is corresponding with the is called **. Despite this being reported to Vodacom and despite my constant enquiries to them, they have not responded or resolved this matter of the fraud and theft they committed (via Elite Mobile) on my contract and bank account.
