Can't understand why itunes.com/bill wants get my money
So, almost every day, or a few times a day there come massages to my phone from bank: "Refusal. Not enough funds ITUNES.COM/BILL, ITUNES.COM online-payment 39.99USD 4*40". I can't understand why itunes wants get 39.99 or sometimes 7.99 from my bank card. I have checked my purchase history, there only one subscription was on june 22 - Apple music 0.49USD for 3 month period. I got it and after 3 months I have canceled this subcription. Purchase history checked, subscriptions checked. Please help me if someone knows my problem.
