How can I return all the money spent?

Good afternoon, my name is Pavel, by the nature of my profession (I am a sailor and owe a debt to the sea) I gave my phone to my son. I have been at sea since November 2019 and only today was able to leave the ship, because due to the spread of the Coronavirus infection COVID-19, our ship was at sea, and then was put in quarantine for a long time, since there was one infected on board. All this time, my son played games on my phone, downloaded new ones, and unconsciously made in-game purchases. All the while I was at sea, he made many purchases after spending more than $ 1000. He made purchases from my cards and I did not know about it. Having arrived home today, I saw that there were no cash on my credit cards, having checked the purchase history I got horrified. I deleted the game from the phone and now I don’t know what to do. Because of the coronovirus, we need money to buy medicines, antiseptics, masks and food, as I am in quarantine and self-isolation at home and do not get paid. I ask you to help and return the money spent. I have never contacted you before, but now I ask you very much to help me get the money back, at least in order to preserve my good feelings for Apple, and thereby try to survive the difficulties in our family due to coronavirus .
