Vodacom lack of service broken promises

I am writing on behalf of a friend Leoni Meyer (ID ***). Leoni had a Vodacom contract that expired in March 2022 and although she wanted it renewed this has not happened. The status of the contract is difficult to determine because Vodacom is not longer sending any statements! Leoni was due for a new phone and specifically asked for a non-5G phone. But, a 5G phone arrived and Leoni returned it. Eventually after numerous calls the phone was cancelled and another one was ordered but was never delivered. Despite endless promises from Vodacom to call back and to sort the problem out it has never done so.
