Contract upgrade = horrible service

From October an agent by the name of E*** has been contacting me with regards to an upgrade, I finally agreed to an update and chose thw device I wanted on the 07/11/2024, agent confirmed deal was concluded and I shud expect delivery in 2 to 3 working days. On the 13/11/2024 and several times after I made contact with rewards co as I had not received my devices, I spoke to Melanie, Bafana and Siyabonga on *** all promised to return my call with an update. Nothing till date, today @ 08h58 I received a call again from rewards co agent Fatima Marimuthu from *** and again she offered me an upgrade I had to inform her I had already done an upgrade went through the frustration of explaining everything again for what felt like the 100th time and again she promised to call me back in 30 minutes, we are now at the end of business and no call back. Subsequent to all of this I called Vodacoms after sale number and had to explain everything again.... all I want to knw is where is my devices and why are the communication skills so bad at this company
