VODACOM MEGASHAKE ENTRY ****

I have been buying MegaShake entries on the Vodacom *133# number for entries into the draw for the Audi A3 in June. I have spent a lot of Voda bucks and have over l50 entries into that specific draw only to receive this sms today "Hi :-) Vodacom ShakeUp: We're giving away cash prizes in May! Note that the Audi car draw was an error and you have been automatically entered into a draw to win a R5000 shopping voucher. Draw date: 3 June 2020. T&Cs apply. Stay Safe. Vodacom." How on earth can a company do this? How does an R5000 voucher compare to an Audi A3??? THIS IS FALSE ADVERTISING and should be reported to the consumer council!
