Cancel In-App pirchase ...

Dear Apple Support team,

My kids were playing on a game on my iPad and purchased a bunch of in-app purchase in a few games (ie. hay day, cookies run, PVZ, Minecraft). Later I'm got the statement from the bank on my spending of total of 136,611 THB (approx. 4,000 USD). I'm not sure if this is a fraud by the game or my kids actually clicked many times on the buy icon. Anyway, the design of the game which popups a "buying screen" every time is very risky to induce this kind of error. And I have no idea as of when did he start to remember the password,

Anyway, This amount is very huge money thus, i humbly request your team to cancel these purchases and refund the amount.

kindly advise.
