Hi @gindavi and welcome to our adorable Community 😊 I can't tell you for sure why it happened but I can redirect you to the post below where you can find out what to do when your purchase goes wrong including the refund option.
I did not order anything, but I was charged $1.99 plus tax ($2.14) from Google play. I wondered if there is an annual fee to play or one tl play without advertisements. I did not get prior notification that I owed anything. I just need to understand the charge even though it's a small amount.
@gindavi All King games come without annual pay or free advertisement pay. I will ask you to fill in the support form here https://soporto.king.com/contact and the support team will explain to you what is happening.
Fill in all the required information and make sure that you are choosing the correct topic (Problems with purchases) and subtopic (Payment queries). Once you fill it in you will receive an automated email message. You need to answer to that message and explain your issue in order for the team to reach you. If you don't answer it, they won't reach you at all.
