can't change password

So, i wanted to change my password, i came to official site of League of Legends, clicked on settings, and then it came, that really scary big title "ADDITIONAL VERIFICATION REQUIRED" and under that, was written that, they emailed me to my Email and sended me a code which they need... but I didn't get the code, I checked my email adress every 2 minutes, waited about one hour, and still nothing. I tried 4. times to re-send code but nothing. Some help with that summoners?[sg-lux-2]
