Hello there, VoodooDaddy0405.
If you have customers who encountered an error message that says merchant doesn't take mastercard, this issue has been resolved already. You'll want to advise them to reprocess the payment. They can also use a different payment method as a workaround.
Let's make sure to enter the correct details if your customers received an error that says "You can try again, or come back later and try connecting then". The name should be exactly the same as what's on the card or the account holder's name. Let's also double-check the zip code, CVV, and the expiration date if they are correct.
I'd also suggest contacting our Customer Support Team again if there's no changes. They'll be able to verify the cause of this error. They can also check if there's an update since you've already reported this.
Let me know if you need anything else. I'll be glad to provide additional help.
