Vodacom Deception/*****

I upgraded my phone at the end of September (or so I thought) on Vodacom's website and received my new phone. The old contract was supposed to end and the new contract was supposed to be a reduced monthly amount. To my surprise, as of September 2022, I was debited with both contract fees. What I learned is that the online agent created a second account in my name without my authorization. It was an upgrade of an existing account and was never supposed to be a 2nd new account. I have tried the call center on numerous accounts but was either cut off or not understood or patronized. I have mailed the ***** department twice, but all I get is an automated response and no further action. This ********** activity is reflecting negatively on my credit record and I have informed the credit bureaus thereof, but they cannot stop the ********** activity on my account. I am with Vodacom for more than 25 years, but am now so frustrated and annoyed with Vodacom's service that it seems the only option here would be to have legal advice.
