Hi
It may help to check that you are presenting your device to the payment terminal correctly and, if prompted, that are you choosing Credit on the payment terminal (even if using a Debit card via Apple Pay).
Detailed instructions are provided here, including links to demos:
Using Apple Pay in stores, and within apps and websites - Apple Support
You may also wish to report your failed payment attempt attempts to Apple here:
https://www.apple.com/feedback/apple-pay.html
Under Feedback Type, options include "Apple Pay not working at the payment terminal as expected" and "Apple Pay transaction declined".
The form enables you to report issues with specific merchants, transactions, card types and issuing banks.
This is a volunteer forum. You are not speaking with Apple and no one from Apple will respond here.
