Unauthorised Contracts

Vodacom has TWO unauthorized contracts in my name, and I have requested that they be revoked and cancelled. I also did not receive invoices for the unauthorized contracts. I did everything they asked me to do from ***** department, Police clearances, bank statements, invoices, signatures… The invoice I get is for my mobile phone amount. But on the monthly statement Vodacom still deducts the other two unauthorized contracts as well. They removed the 2 contracts from my mobile app, but I am still paying for the 2 unauthorized contracts. They still haven't revoked the unauthorized contract. And this is the second debit order to go from my account since I reported it. This is 6 months unauthorized debit order being deducted.
