fraudulent
Fraudulent. The bank or Stripe suspects the charge is fraudulent.
Will retrying the charge work?
No. The same card will keep failing. You need the customer to give you a new payment method.
What to do about it
Don't retry. Stripe recommends presenting this to the customer as a generic decline. If it's a long-standing customer, ask them to contact their bank.
What to tell your customer
The payment was declined. Contact your bank or use a different card.
