Lied I feel like this too but it seem like they doesn't have any refund method and haven't the time to go on a random things to make an artificial gacha for a random player too so they done this. I haven't to complain but it's sure some peoples will feel like it's steal, It was 3 month I wanted a refund or anything too but they are very kind it seem.
And VDD the 3 next event are slice type :I
