Injustice experienced from Game online. Don't buy from them!!!

I was one of the lucky few to enter the coupon code BF2023 and it dropped the price to R5200. I have proof of that as I took photos of the whole event. I went to checkout and everything was fine until I had to select the method of payment then suddenly refreshed my screen automatically and told me my cart was empty. Absolute nonsense. Thank you Game, you lost a customer for life.
