Daylight *******

On Nov 25th I app**** for a wireless 5G deal for R499 and I didn't get any response for 48hrs. On the 29th I walked in store and got the deal. This deal came with a R1000 Makro voucher and 12 months Disney +. I was advised I'd receive the notification via sms. 2 days later I went again and I was told to wait for an sms from MTN. After a month in December I enquired via social media and was told to ho back to the store as my promotion was not loaded. There I was advised that due to a system error this didn't go through upon activation of my contract and thet would contact a team to assist. After almost two weeks I was advised that there was nothing that could be done. The voucher had a limit to number of customers and for Disney + they could do nothing because the promotion had lapsed. How is any of this a loss for me when I activated my account while the promotion was still valid. Their system error is not my doing so how is this issue an impediment to my obtaining what is due to me? In all honesty service providers in SA have half ****d customer service and no one holds them accountable. Where is the consumer protection act protecting consumers? Is it right that a system error, their system error be the reason I don't get what is due me as advertised?
