Accidental shop purchase

I was at the home screen, locked my phone and put it in my pocket. Took it back out later and there's a card on my screen. Turns out I managed to get into the shop and make a purchase. Bought the Charizard ex Premium Collection for 2,000 crystals. Best part is, I already had the promos and sleeves from that because I bought the physical version and redeemed the code card...

Contacted customer support and they won't do anything for me. How is there no confirmation button when making a purchase from the shop? This is so ridiculous. I'm so mad about this. I've been saving my crystals for months and now I'm out 2k for a useless purchase. I already had the sleeves and 10 copies of Charizard (who I never even play) so I got 6 packs of 151 for 2k crystals, when if I truly wanted to buy packs, I could have gotten the same amount for only 1,200 crystals. I'm pretty sure there were other purchases made because I'm missing more than 2,000 crystals but I have no way of knowing.

I can assure you that customer support can see what I purchased and can see that I've never spent crystals besides to unlock the Premium Pass for Battle Pass but they just give me a canned response: "Unfortunately, we are unable to offer refunds or exchanges for in-game items in Pokémon TCG Live for any reason, including if the items are unused. Please be careful when making selections. We recommend ensuring that you are playing with a stable, strong internet connection to prevent connection issues that may affect the purchase process. We apologize for the inconvenience."

Seems like they don't even understand what I told them and just give a generic reply. "stable, strong internet connection"... I enjoy the game/app and my kids love using it too but I'm so disgusted right now that I'm probably going to uninstall and stop buying any physical Pokémon products altogether.
