*********** call center service for changing debit order details

I called on 20.12.2023 to give the details of my replacement American Express card for the monthly debit orders and was told that I will receive a call within 48 hours. I only received a reference number A2-Y***-5DPSP but never got any call. So I called again on 27.12.2023 and the agent apperently logged a "call back" again, which never happened. Today I receive a SMS that my Debit order was successfully removed!? I am not willing to spend another half an hour wasting my my work time waiting in line for calling your call centre, unless Vodacom would comopensate me for this time, Please make sure that finally someone competent will call me in order to sort this out, so that all payments will be debited from the renewed credit card. The service receicved so far is just not existent and insane for a company like Vodacom...
