Match doesn't accept and Lost my Promo

Good Day. Riot please note that i lost my promotion just because there is a bug in your client aswhere i click accept, and the damn thing just freezed. I had to restart my client just to log back in and see i lost LP point and i have to win all over again. This is not completely fair to players that really try to play and win to rank up just so that a idiotic bug can ruin their day and make them lose what they worked for. Please see to it that this is sorted out before you even think to buff yasuo or yi more, because that's all you seem to do. You don't care about the small bugs that can ruin your day, make people quit league
