7 million gauranteed rewards BS

Mc Donald's…… Zwartkop centurion. I bought a meal this morning was given a scratch card. as apart of the 25 years celebration. I scratch the card .I have a different reward option, so I redeem one of them only to find out the coupon number doesn't exist. look I'm not a petty person. on numerous occasions I've gotten poor service from Mac d's and looked it over , but what kind of nonsense is this. for me this is promising and not delivering. please sort out your story there. don't get fool by the attempts to lure you in by telling you. you will get guaranteed rewards. dololol. what a waste.
