Requesting Refund and Security Review After Unauthorized Brawl Stars Charges

On May 23, multiple charges were made to my VakıfBank credit card under the name "Google Brawl Stars/London," one after another, without my knowledge or permission. The amounts shown on my statement were $6, $3, $6, $3, $1, and another $6, adding up to a total of $25 in unauthorized charges. These transactions were not made by me, were never approved in any way, and I never requested any purchase. I haven't shared my password, card details, or any verification code with anyone. Despite this, these amounts were charged to my card through the company in question. I'm requesting that all $25 in transactions made through Google Brawl Stars/London, which occurred entirely without my knowledge, be immediately canceled and refunded to me. I'm also requesting that the necessary investigation be carried out regarding these unauthorized charges, and that security measures be put in place to prevent this from happening again.
