False advertising

I've never been disappointed in a service like I am with Vodacom. Purchased a phone at Ackermans Kenako mall, it was on Vodacom promotion that you buy a R29 Vodacom airtime and you get 16 gig data. Did I receive it ?? Hell no. Logded a complaint with the store and it was escalated with Vodacom and a representative from Vodacom named Ncedo Mjekula called and advised that he is aware of this problem and has escaled it to Unbranded Escalation Desk EC-1MF2-2TL2AP and gave me this reference. Been doing a follow up with him and have received no response from him. Vodacom should I discard this simcard?????
