If that is of no success, then give Apple a Direct Call:

As you might suspect, no one here would know the reason for the occurrence, of course. So, contact Apple. They’ll know why this occurred and will run you right through how to fix.

Contacting Apple:

• Contact Us - Choose Locations
• Proceed from there as necessary
• Note: Phone calls are taking a bit to go through at the moment, due do lots of calls. With the Coronavirus Pandemic, many are at home at the moment, with much time on their hands to contact Apple. So, just stay on the line, and you will get through :)

For Note:

Why Accounts Become Disabled:

There are quite a few reasons as to why this may have occurred. Some possible reasons include:

• Too many unsuccessful login attempts
• VPN (Virtual Private Network) usage
• Disobeying Terms & Conditions
• Consistent transactions
• Session Times Out
