Horrific service

I upgraded a data sim as per an advert on fb. The upgrade lady who answered me told me all good upgrade to 50 gigs data 50 gigs anytime data and 50gigs night owl would kick in 1 September. Now when I try to connect via router it does not allow me to access and I'm told by upgrade dept my order was canceled I am on my old contract of 30 gigs and the cherry on top I cannot access any data as it says it is completed in one day. Spent 3 hours on the phone. No help from customer care, no help from upgrades yet I'm paying my account. Vodacom your service is horrific and you agent did not know what she was doing when I was accepting the conditions of the contract. This is wrongful advertising of a deal on fb and your red hot deals and you are breaching the CPA. Call me to sort this out. You did not even let me know YOU CANCELLED THE UPGRADE. I WANT THIS SORTED OUT AND I HAVE AN ORDER REF CONFIRMING WHAT I ASKED FOR AND WHAT YOUR AGENT AGREED.
