Vodacom not Cancelling / Reversing Orders leading to charges for nothing

I placed an order at Vodacom Online on Monday 6th March 2023. Five minutes later i had to call again to request a reversal because i realised the device i took is not water resistant. I spoke with consultants in Cancellations, Reversal, and Customer Care who all confirmed that the reversal will be effected.

It has been a week since i called for the reversal, the reversal has not happened or cannot happened. Every day i go through the same process or questions with consultants, promised that the matter is escalated to Manager but STILL THE REVERSAL IS NOT HAPPENING.
