Main account permanently suspended for account sharing

Hey there, in Februar my main account got permanently banned for account sharing after it got scammed by some guy from Germany (all the Riot emails were suddenly in German). After some talking to Riot a random employee sent me a response stating that my account had been permanently suspended due to account sharing. I've sent multiple tickets to Riot, none of them seem to have been read by any employees since I keep getting the same answers over and over again: Account banned blablabla account sharing blablabla we won't change our decision. Did anybody else have this problem? I've been playing league for over 5 years, spent over €400,- on RP and then I get this as a thank you... Nobody even takes the time to help me with this issue... Edit 1: Hacked changed to scammed
