GAME STORE IS A ****!!

Game is a ****!! I have been paying my debt with them but it's not going down. I paid R354 in January 2023 but instead of my debt going down with this amount, it only went down with R90,94. The same happened in December of 2022 I paid R1000 and the bill only went down with R850. I'm feel like I'm not gonna finish paying this account. I regret opening an account with them!!
