Failed upgrade

Good day I writing this email with huge disappointment with my recent upgrade.

If you can check on your system I upgraded my contract to an iPhone 12 64gb black on the 10/12/21,only to find out a week later after I had to call back that the upgrade was cancelled due to no stock. I re-upgraded again on the 17th of December to the same phone different color iPhone 12 64gb blue cause I was advised that their is stock of it. I have been waiting since for the delivery of my phone with numerous calls back to Telkom to find out what the hold up is. Today I called and after being unable to get through finally got through to an operator who said there is no stock of the phone. I asked how come no one has sent me mail or sms or a call to make me aware of this. All I have been getting is apologies with no solution. I am very displeased with this service. My contract is 21days in and at this rate I can see I will be paying for a phone at the end of the month but still not have a device. I would appreciate for this matter to be escalated and my device delivered to me or have the upgrade cancelled.
