Vodacom poor service!

On 2 December 2020 I did an online deal to upgrade my existing contract, Ref R51GQ8 and as per the SMS A call center agent will contact me within 24 Hours. No Call, on 7 Dec 2020 again called just to find that they had no such ref no. nor any deal, again I upgraded with Ref ***6 and they will send me an email, still waiting for the email. Today 22 December 2020 I again called at 11h00, first they say the cannot access the system and will call be back. Needless to say no call, Again I called Vodacom at 15:50, they say they are waiting for confirmation, confirmation for what? Now the call center will send an email to conformation but they are not allowed to copy me in. Vodacom keep your contract and your cell phone!
