Riot Games Banned My Level 355 Gold Account with Full Collection and Bundles

Today, all three of the accounts I created were banned by Riot Games. I even formatted my PC and installed five different antivirus programs—none of them found any pirated or suspicious files. Still, Riot keeps banning my accounts. I had a level 355 account in Gold rank with a fully completed collection worth ₺5832. It also had three special bundles. I am requesting a replacement account with the same content. I’ve attached a screenshot below; that account was the one I opened around 5 PM today. I have always been against third-party software, and I just want Riot Games to give me back my account.
