What is

Discover Reason Code NA

?

The cardholder says this transaction should have been voided but was still charged.

Why this happens

A transaction was voided or cancelled on the merchant's end, but the void wasn't properly processed before settlement.

What this means for each merchant

Your void/cancellation log is the whole case — confirm whether the void actually completed.

Evidence that typicalls wins this
