Vodacom ShakeUp - Audi (etc) draw entries bug

With Vodacom ShakeUp I actually did win some useful stuff, e.g. data (thanks for that). Amongst others, I have also won several entries into draws, e.g. to win an Audi A3, UBER for a year, etc etc.. These draws are all on 21 Jan 2020. ... but alas, all these draw entries are only valid until 31 Dec 2019. My logic tells me that the same probably applies for everybody who "won" these entries in Dec 2019 (?). What is the point in letting people "win" these entries if they are all automatically invalidated on grounds of expiring before the actual draw date ?
