guest checkout purchase but no confirmation email ...why????

Contact - How to Contact Us - Apple

Not being familiar with your bank I can't say for certain, but that looks like the purchase was authorized, not that its actually been charged to your credit card. But we are all just fellow users here. Contact the Apple Store and inquire as to the status of your order.

BTW, it's a really bad idea to post screen shots like this or other personal information. This is a world-wide public form, seen by millions of people, so you can't know who could take advantage of such information to do you financial harm even from such relatively minimal disclosure as this.

Regards.

Phone only, to the best of my knowledge, for orders that have already been placed, though you can try going to the main Apple Store page:

Apple Store Online - Apple

and clicking the Ask a Specialist link at the upper right. There's a chat option there, but I don't know if they can help with existing orders.

Regards.

One way or another you certainly will get what you paid for. It's possible that this being a Sunday the confirmation email is just slow in being sent. But contact them and they can sort it out. Worst case is that you can report to your credit card company that the vendor lost your order, so you won't be out what you paid, but I very much doubt that will be necessary.

Regards.

I suspected an error in email address, but of course had no way of knowing. Glad you were able to get things sorted out. Enjoy your new iPad!
