Unauthorized Family Farm In-App Purchases Charge Player's Debit Card Twice

I recently discovered that money was deducted from my account while playing Family Farm, despite never selecting a card or confirming any transaction—in fact, I even canceled the process. Two separate charges were made from my debit card: approximately $7 on March 24 and approximately $11 on March 26.

I absolutely did not authorize these payments. Even though I made no purchases in the game and canceled the prompt, money was drawn from my card as if I had approved it. I play the game on a tablet and do not understand how this happened.

I have not yet contacted my bank or any customer service department regarding these transactions, and I do not know where or to whom I should apply. I demand a full refund for all amounts drawn without my knowledge or consent. I request that necessary security checks be performed on my card details and account, and that my issue be resolved as soon as possible.
