Apple has unilaterally disabled my account and told me to create a new one. They will let me know in 5-10 business days if they will refund the balance in my account.
There is a slight chance that the refund process will resolve the account issue as it is being elevated to an engineering team in the fraud department.
I emailed tcook@apple.com and the Executive Relations team reached out to me. I was able to provide everything they asked for and they handled getting my account unlocked. They told me to go ahead and reorder the Studio the same way I did, as I had a window where their automated system wouldn't be involved for my account. I did so and am now REALLY hoping that my account doesnt get locked again!
My Apple balance is locked and unusable though. I'd like that to be freed up, and I'd still like to buy the Studio!
Really hoping that it gets sorted out. I had no idea gift cards were such an issue; I rarely use them.
