Vodacom so *********** and cannot assist to cancel the sim-only deal

I app**** for an online sim-only deal contract for 20 GB on the 17th March 2023 because I was advised by a Vodacom consultant that this data can be credited to my prepaid number but after receiving the sim on the 20th March 2023 I was told it cannot be done I will have to cancel the contract and re-apply over the phone so they can ensure that the data is credited to my pre-paid number, and so I contacted *** to cancel the sim-only deal but I was told that it can only be done by Sales and Upgrades on ***4 and spoke to Felisha Naicker on the 27th March 2023 and she told me that she is going to escalate the query and copied me on the email and this was done within the 14 days cooling off period. so i started requesting feedback from the 28th March 2023 and on the 29th March 2023 Lennon Samduth responded that it is still pending and I asked for update on the 30th March 2023 and on the 03rd April 2023 Felisha responded that "Apologies for the late reply.The reversal has not been done as yet however the request was closed so I have emailed for feedback now." and today I asked again for an update she rep**** that "Please call *** for assistance we cannot reverse." so I am so disgusted and angry about Vodacom service because since the 27th March 2023 asking about one thing to cancel the sim-only deal and only today after 8 days I'm told that i need to contact *** but sadly when I called the number they are asking me for an access code so what will it take for me to cancel the sim-only deal, i have been with Vodacom for a longest time and have 3 active contracts but their treatment towards me is wrong and I will never tolerate it at all I'm frustrated now and disgraced at their level of incompetence
