Poor Service & Communication

I was approved for an upgrade on 11/11/2022. I had requested that this or some sort of confirmation be sent to me & was not done so I called in on the 14/11/2022 to enquire. When I called in I was told that there was something pending & nothing approved. They had told me to cancel what was pending on the system then reapply in which I did not knowing that my Iphone 14 Pro was already approved. Then after reapplying I was told that I am conditionally approved. When I called back I was told that I the upgrade was approved & the lady who had assisted me would call me back. I called back again as I still was not called then I was told that I am conditionally approved. They would get the lady to call me back. I had called back again & spoke to someone else who told me that she would get the lady to call me back but still no call & my frustration is growing. I eventually called through & spoke to the lady Nadine who I had initially spoken to on the 11/11/2022 who then told me it shows approved & the 1 that Kgomotso had made me do shows conditionally approved. I was put to Mondo & Mondo said that the contract is approved approved & not conditionally approved. I then got confirmation that is is approved & not conditionally from Nadine. Then Kgomotso called me & tells me it is conditionally approved. I am now at my wits end with this. Since I was 1st approved for my Iphone 14 Pro Contract upgrade, I should be going around in circles like this. Please could someone very senior contact me & also push through this contract & have approved. As a customer I should not be going through this. I shall be going on the email that was sent to me that the contract is approved & take it as final approval.
