early cancellation complaint

Did an early settlement on my account (4th) and got debited month end (25th), called Vodacom to advise that I reversed the debit order as all benefits were revoked by them the day it was cancelled (5th of month), spoke to Sipho 27/09/2023 @ 12:27 and was advised that I would be contacted within 48 hours, no call recieved, sent an email and asked for an update on my query, still no feedback, resent my email and asked for an update, but still no feedback

Account still shows an amount outstanding and nobody seems to want to resolve this
