Vodacom online upgrade struggle

I have done my cellphone upgrade on-line on the 6th of July 2022. I have placed an order for a Samsung S21 and received an invoice stating that my phone will be delivered. On the 11th of July I called customer service since I haven't received my phone. They told me that they cannot see my order on the system, but it will be escalated and they will call me back. I'm still waiting for that call. I then called the upgrade department which informed me that due to a system error, no order number was generated but they will log a call for it to be generated. The person said it normally takes up to 48 hours. I called back on Friday, yet another person told me there's no order number, but then followed up with the first person I spoke to which said it was escalated to her supervisor but she is still waiting for a response, she will call me back during the afternoon. No call received. I am still waiting for a response from vodacom and am still without my new phone. I must struggle and keep on following up but it was a system mistake from their side. Terribly disappointed.
