Ok, here's my problem. I've won a giveaway (Bunnyfufuu's) and it involved a 10$ Rp card. He took 8 days to send but anyways I play in euw server and the card code he sent me tells "not valid in this region" when i redeem it, as it is probably for NA. Could anyone help me out and tell me how I could redeem it in EUW or exchange it for an EUW code ?
Here are some screenshots proving this (not cropped)
