Q: Why is Apple Pay not working at Office Depot?

Hi

You can report your experience at Office Depot to Apple here:

http://www.apple.com/feedback/apple-pay.html

The feedback form enables you to report issues with specific merchants, transactions and payment cards, so is very helpful in enabling Apple to investigate.

You are most welcome!

If you experience any further issues in future, be sure to send a new report each time.

Apple may never respond to you directly (as the feedback form explains), but they will certainly read your submissions, which may help them to address any underlying problems.
