Apple ID deactivated/suspended

What can I do about getting my Apple ID reestablished it was deactivated/suspended due to some transactions I had posted on my Apple Pay that I did not recognize because apparently I was logged into all devices and instead of calling Apple I called my bank directly and disputed the charge thinking it was fraud I was never told nor was I explained that after 3 disputes/transactions having to do with Apple Pay and ID they will deactivate your Apple ID and user name and I am devastated because I’ve had it since I bought my very first iPhone back in 2005 I have my entire life linked to my iCloud account including my son who recently passed away all his photos text messages and voicemails will be deleted if I log out of my old ID and create a new one please help I’d like to have my old Apple ID reactivated so that I can keep everything I’ve had on my phone and in my 2 TB storage for the past almost 15 years
