Purchase history is gone for my past 9 years of playing the game.

How come that happened ? Never got notified about that change, got no clue how much money I've spend on the game. 1 refund left but nothing to refund. Going to quit this game soon and wont deal with riot games anymore at all. Like why take 9 years of history out of my account without my approval. A complete waste of time going to play Heroes of Might and Magic 3.8 now, not this pretend to be a legit game. 1 refund and my purchase history of more than 2000 dollars is gone. Pretty much them took my possible over 2k rp refund. No good. I did read about them having a new thing of recent 30 days purchase history but i do not recall them making that update and asking my approval if I knew about that thing sooner I would have quit this game already or said no to this. Last thing i remember it having my whole purchase history so I could literally count up money I've spend on this game but not anymore. Not anymore a good game to me personally. Like what do I refund now? My BE purchased champion. Hell no i got 140k BE. Instead of removing my RP purchase history how about them making a good way to spend that BE.
