I want to buy req packs in halo 5, but I cant because I didn't change my purchase settings, I try to change it, but I cant because i need a parent to. I'm just confused because I was born in 1990 and my account birth date is correctly set at 1990. What the hell doe sit mean I need a parent to? Is it like an account? If it is how do I know which one it is? Please help, thank you.
