Telkom Upgrade

On 25/08/2020 I upgraded my Telkom contract on their clearance special for an iPhone Xs Max 64GB. The delivery took place on 03/09/2020. Telkom delivered an iPhone Xs 64GB. I made contact with the upgrade agent and she arranged for the incorrect device to be uplifted and replaced with the correct device. On 08/09/2020 the incorrect device was uplifted but to date I have not received the correct device. My number has been inactive since 03/09/2020. I have contacted the agent numerous times to resolve the issue to no avail. I have e-mailed the agents' manager and he has not responded to any of the e-mails. I have contacted the upgrades department asking them for either the agent or the manager to contact me but still have not been contacted. It is very frustrating that it is so difficult to get feedback and to be without my number for such a long period. I cannot perform any banking and cannot be contacted.
