Vodacom is full of ****

I am so upset with the service received by Vodacom. I tried to cancel a 20 gig data order/upgrade that I placed 14 days ago. I was told I am still within the cancelation dates when I first called on the 9th May 2019. I went into one of the branches to try to cancel this upgrade which I now realize was incorrectly stated, the upgrade specialist said I would pay R199 for 20 gigs however it seems this thing is over R400. I explain that I will rather upgrade to a device instead of this 20 gigs because I had just been ****** and no longer have a phone to even use the 20 gigs. The call center agent and branch stuff confirm that it has been requested for cancelation, but advise that I cannot upgrade to a device pending the cancelation which takes about 7 - 14 working days (how ridiculous) Vodacom is essentially saying I cannot be reached or have access to any device unless until 14 working days.
