Upgrade not fulfilled and cellphone not delivered

I've upgraded my contract on the Vodacom App on the 29th of November and the order was approved and processed and is still showing as processed on the App currently. The order also shows that RAM couriers will deliver the order but I have not received a call from them for delivery as yet. I have called Vodacom twice before on *** to try and find out why I have not received my order because Vodacom, at application, has indicated that delivery will take place within 7 business days. On both occasions, both the consultants told me that it shows that the order was canceled which I never did. They also said that Vodacom tried to contact me on certain dates and no Vodacom numbers are shown on those days on my call history and I did not receive any messages or e-mails from Vodacom to that effect. Both consultants told me that they will escalate the matter to the relevant department and that someone will call me back to resolve this issue but nobody called me back. Could you please urgently ensure that the order is fulfilled with the same benefits and same monthly premiums as was advertised and approved and processed by Vodacom on the 29th of November?I would appreciate your prompt and urgent response to this matter.
