Vodacom upgrade reversal

On the 26th of April 2024,I got a debited an amount that was bot agreed upon by Vodacom,after investigations whgere made,we discovered that a wrong upgrade was made on a Vodacom contract that was suppose to be cancelled. The counsaltant on the other line of the call was Gabsile Fakude,she assured us that she launched a upgrade reversal,and Vodocom would contact us with 72H ,it is past 72H ,as I am writing this complaint on the 5th of May 2024. This worries me ,as they will repeat this again this month and i will have to have a back and forth with them. i am utterly dissapointed ,just as I had praised them previoulsy ,they just cant seem to stop on wanting to dissapoint their clients. And no case /reference number was given for me to do a follow up.
