Riot Games Ignoring My Stolen League of Legends Account

My League of Legends account was stolen, and years of effort and progress disappeared overnight. The email, password, and all account details have been changed, leaving me locked out. I immediately contacted Riot Games support, expecting assistance in recovering my account, but their response has been unhelpful and dismissive.

It should not be this easy for an account to be stolen, and it certainly should not be this difficult to get it back. Riot Games either isn’t seeing my requests or is deliberately ignoring them.

I need urgent assistance in restoring my account. I have all the necessary proof of ownership. Riot Games must take this issue seriously and help me recover my account!
