UCOUNT STINKS

I tried to redeem my Ucount rewards at Checkers hyper , after the Standard bank sent me an SMS with the relevant details and voucher numbers etc. Lo and behold after trying at two different stores I find that these vouchers have already been redeemed or have expired when they are only supposed to expire in 2024. Standard bank you are skating in incredibly thin ice. I swear I'm going to put my money into another bank if this is not sorted pronto. I don't care which bank because they all stink to the heavens but I will do this.
