Unauthorized Google Play In-App Purchases Drained My Savings

My young child made what appeared to be nearly 50 consecutive in-app purchases without my knowledge on July 25, 2023. The total price of these purchases was 3,870.68 TL. My family cannot afford to pay such an exorbitant sum because we rely solely on a single income. I'm reeling from the utter devastation and agony I'm experiencing. I request you, I could not possibly make it without your assistance. I strongly urge that these purchases be canceled immediately and that the full amount be refunded to my credit card as soon as possible. I am in complete financial ruin as a result of this situation, and I sincerely hope that you understand the gravity of the situation as well as the emotional toll it is taking on me.
