Urgent action required on your Apple order W*********

I received an email from Apple (4-5days after order) saying urgent action is required for my order, they directed me to call their number, else my order will be cancelled.

I called the number, only voicemail box was available, before I could record the details required to ensure a call back the call would get cut. Tried two-three times, but was unsuccessful.

I subsequently received a mail saying that my order was now being processed.

I'm confused.
