Chamet Unauthorized Charges From Child Purchases

I am writing about several unintended purchases made in the Chamet application by my child, which caused a serious financial loss to me and my family. Through this app, my child bought diamonds and used them in the game without my knowledge or permission. As a result, approximately 460 OMR was taken from my account. These amounts were charged in one‑time diamond purchases and the money was directly cut from my Bank Muscat account in Oman. I did not approve these payments and I only noticed them after the money was already taken. I contacted Bank Muscat about these charges, but they informed me that the problem is related to the Chamet app and that they cannot help me further. Therefore, I am now addressing this issue to Chamet and the relevant parties. I request a full refund of the total amount of around 460 OMR that was spent accidentally by my child, and I also request that my account be protected so that such purchases cannot happen again without my clear consent. I ask you to review these transactions, consider that they were made by a child by mistake, and return my money as soon as possible.
