When you create a ticket to Riot's support, don't "bump" it with adding messages.
That action can delay your ticket !!!
-> Very inmportant
Don't forget Riot's support receive a lot of ticket every day ! So they can't answer to you in only 1 hour. And then the recovery of account can be difficult.
So BE PATIENT !!!
I think english support needs 1 week to answer you.
-> Beware of website !
A lot of websites looklike to official League of Legends website can offer to you free RP, skin, champions ...
Be careful ! These websites get back your personal information. Never give them your login and password from your League of Legends account !!!
None Riot's employees, none "partner website", none sale needs of your password.
The only place when you have to use your password is on PvP League of Legends and in the official League of Legends website.
