your shop = my disappointment, can i get a redo?

champions i got a skin for in your shop:

: played literally 1 time in last 2 months and it was a random in aram : played 3 times ever, twice in july, dont own him, 2/3 was random in aram, the third time was forced in one for all : played twice in the last 2 months, once was random in aram : played 5 times ever, 3 were random aram, 1 was custom after buying her to see how she worked, only played 1 time in last 2 months : 4 times ever, 3 were aram, 1 was forced one for all, only played once in hte last 2 months, also have a skinshard for that skin : twice ever played, 1 aram, 1 forced one for all, dont own him, only played once in last 2 months

Champs i shouldve gotten a skin for: : 15 games in last 2 months, 9 were normal summoners rift, 6 were aram : 14 games in last 2 months, 10 were normal, 4 were aram

This is legit bonkers. Isnt the system supposed to choose champs for you based on your match history? Can I ask for a reroll of my deals? It literally cant be anymore useless than my current shop. I'm literally at the point of "take my money" but yourshop is blocking me rn.
