Incompetence has no boundaries

Received a call from Cell C (084140) on the 20th of November 2015 regarding an upgrade. Went through the entire upgrade process, accepting the terms and conditions, confirming details etc for 13 minutes and 27 seconds. I even rated the agents' service. Since they had stock of the handset, I could've expected the phone on the 23rd of November 2015. Cell C phoned me on the 25th of November 2015 to tell me they'll deliver the phone on the 27th of November 2015. Today, 2nd of December 2015 I phoned Cell C to follow up on the delivery, and now I am being told that the upgrade was never captured - apparently I am not even due for an upgrade. Exactly how *********** are your agents? I have the full (upgrading) conversation recorded, and after listening to it again there has definitely been no misunderstanding. I am now sick and tired of your guys constantly *****ing up. Sort this **** out, I need my new handset by the end of this week!
