Shocking service with no feedback.

Dear Vodacom, your online service support is shocking. Since the 4th of August 2020 I've been trying to upgrade. A system error on your side caused the upgrade not to go through, no communication or feedback from Vodacom, sitting at home waiting for my new phone. On the 7th of August 2020 I followed up just to be informed that there is no upgrade in progress on my profile most probably because of your system glitch. This was then fixed and I then received a call back from your service department on the 11th of August to inform me that I can now upgrade, but the deal I requested on the 4th isn't available anymore. I raised a complaint via email on the 11th of August, no feedback received on ticket 68096. I then complained on Vodacom's Facebook page on the 16th of August 2020 and received a call from the service department on the morning of 17 August 2020. Being transferred to the service department I was just transferred to an automated answer where I should rate Vodacom's service and then the call dropped, I got a message on Facebook messenger to thank me for taking the call and I rep**** that the call dropped they should please phone again that everything is logged on the same call or reference number. 3 days later I'm still waiting. This is really disappointing service and at the moment I'm looking at changing my network from Vodacom after being a loyal customer since 2013.
