I just bought a gem refuel bundle, not only it charged me twice, but the game was trying to charge me for a third time, and I didn't receive it. I sent a ticket to them, and they answered me to clean the cache and reinstall the game. It happened many times before, and usually clicking to buy the bundle again would give the item, but not this time. Great way of scamming your costumers 👏👏👏. At least I was refunded the second charge, but no itens received, just wasted money.
