Đánh giá về Xbox Subscription Code (US)

It works great for the second year I'm getting it! Important: USA region code when you redeem outside the USA, don't forget to turn on VPN with the USA region, otherwise error pops up.

It says "This code wasn't found - try re-entering it. If the code is damaged, contact the seller. Invalid characters are A, E, I, O, U, I, S, 0, 1 and 5.". Can you check spelling on your side please> Thank you!
