I would like to restore my disabled apple account
My apple and iTunes account has been disabled because I used to share payment details on a Mastercard with my boyfriend and I tried to make a subscription on one app and the payment didn't go through, so when my boyfriend called Apple due to a deduction of funds in his account, he didn't know it was from my me and Apple disabled my account. Most of my apps now need an update and my account is disabled. How do I fix this?
iPhone XS, iOS 12
