Charged for an admisnistration upgrade - when no upgrade was requested

I was charged on the 01 September 2017, R150 upgrade administration fee, when I never requested an upgrade. Trying to resolve this matter is futile. I have spent more time and money on trying to resolve the matter than the R150 is worth. I logged a call the 19 September with customer service to start the credit process. Today, the 11 October I get told the reference number was not resolved and it was closed. I need to log another reference with another department. I have gone from customer services, to accounts, to the upgrade department, back to accounts, back to customer service. 30 minutes spent on my Cell C phone with different departments and still no resolve. This does not include the time and money I spent a month ago, going from pillar to post. Vodacom just *****s your money and takes no accountability.
