I am begging you for help
I need urgent information and help. My child using iTunes made a bill of over 700 pounds without my knowledge. All purchases were added to my o2 account and deducted from my bank account yesterday, after this transaction I have a negative balance - £ 234. I don't know what to do now, we haven't been working for 2 weeks because of coronavirus, the balance is negative and I'm a single mother. My child has his phone which I pay monthly on the o2 network. The phone was not secured in any way and I know it's ridiculous but I didn't even know that in this way you can use iTunes or any service - I mean making a purchase on iTunes and charging a bill on my mobile phone bill. Can any of you help me? Is there any option to ask Apple for a refund?
