Vodacom issue winnings that are expired

So in December 2022 and before I have accumulated Vodabucks and I noticed when you go to the store they are not redeemable. Finally on 30 December 2022 I phone Vodacom call centre to complaint about the vouchers I won using vodabucks. The agent want to push the blame to me and claim the vodabucks are perfectly working but here on hellopeter we have people complaining. She promise that she will escalate my complaint and they will get back to me. To this day I am still waiting for Vodacom call centre. Vodacom must remember that advertising false competition is an offence in South Africa and competition are regulated . So I will continue to place my complaints with the relevant unit that regulates competitions . I know the vodabucks are too little but it’s a matter of principle that matters to me not the value. I urge everyone to complaint about this vodabucks that can’t be redeemed
