I had the same!! Called Apple and got the payment sorted. Awaiting PFD..13th-20th club
Just got an email saying payment couldn't be accepted.
Tried to authorise a new card, that got declined too. Called up and it still wouldn't work and I have been told to call my bank
On the phone with the bank now, think I am on hold, but the line is silent
FML, why is it this difficult to spend over £1k on a phone!
