Disappointment

So, I did an upgrade on my contract on Tuesday, 10th January 2023 After it was done, I had re-read the specs of the device and was not entirely happy with my choice. I immediately called Vodacom to cancel the upgrade so that I may redo my upgrade with a different device. The call centre person told me they "processed" the cancellation and that it would take 24 to 48 hours and then I will be able to redo my upgrade. They also said that I must not accept the device should it be delivered. Yesterday I called Vodacom to follow up on my cancellation process, I was told by THAT consultant that no cancellation had been processed on my profile, she would escalate it and be in contact with me during the course of the day. Obviously the day had come to an end and she did not call me back! This morning the Courier company called me to ask where the device should be delivered, I informed them not to deliver as I have cancelled that order with Vodacom. At about 10am I called Vodacom to follow up on the cancellation The consultant checked my profile, and yet again, he could not see a cancellation. I asked to speak to a Supervisor. The "Supervisor" that came to the phone was so "helpful" and "willing to assist" She said she would contact the courier, who needs to cancel from their side and she will then speed things up on her side so that I may redo my upgrade. She promised that she would call me every two hours to keep me updated on the process. Four hours later, no call from her. I decided to call Vodacom again. Once again I was told, After Sales cannot do a reversal and the order has not been cancelled yet. I am livid! Been sent up and down by various consultants, "supervisors" and "managers" I mean seriously, how difficult can this process actually be? The broken promises that I have been made by Vodacom employees is totally wrong! How can they not see any activity on my profile? I've been a Vodacom customer for more than 20years! I have never been this disappointed in their service as I am now. Its now been much more than 48 hours and I still cannot redo my upgrade! All I need is for my order / upgrade for this device to be cancelled / reversed so that I can redo my upgrade with a different device.
