CONTRACT FULFILLED BUT DEBITS CONTINUE

Entered into a 2-year cellphone contract, expiring 31 October 2022. Conscious that cancelling cellphone contracts are generally a problem WITH MOST SERVICE PROVIDERS, I spent one hour at Vodacom Clearwater Mall on the phone to *** ensuring that my bank account would not be debited post 31 October 2022, opting to go the prepaid route as explained to the consultant. My bank account was debited with a further subscription for November!!! 😡😡😡 I had my private banker reverse the charge. I recently received notice that December's subscription has been debited (approximately R100.00 MORE than the contract amount) which amount I will instruct my private banker to reverse! In trying to solve this ridiculous situation, I phoned Vodacom contracts number ***; the automated voice rep**** that this number was NOT FOR PREPAID CUSTOMERS! 🤔😅😅😅 Vodacom are therefore admitting that the cellphone number in question is on a prepaid contact!!! If so, why then t8 continued debiting of my bank account?
