How to resolve unauthorized iTunes purchase from a deleted account?

So, i suddenly had a notification from my bank account about a big sum of money for a student. And it is from iTunes which I deleted the moment i got my iphone (sorry apple). I do not have any other family members with iphone so no one could use my account to purchase anything from my account.

The article everyone sends here does not apply in my situation, I also never got any email about the “purchase”.

Anyways, if you have the same issue, I downloaded an app “apple support” and in there if you scroll to the bottom there is an option for a chat (if i remember correctly). The lovely support person told me that there is no subscription on my account (which is not surprising), so she gave me a phone number to call the security center. Unfortunately they do not work today, so I’ll have to call them tomorrow.

I guess I will update you as things progress..
