Help for Payment Alert

[JokerTM]

I got this message today "The user who paid the MM fee has triggered a payment alert. Please do not continue with the transaction until EpicNPC has replied to this chat. We will try to review this payment as soon as possible, but it can take a few hours depending on the time of day. Sorry for the inconvenience."
What should I do now?

Transaction #163437

You have to wait for an update in the chat.

Please do not continue with the transaction until EpicNPC has replied to this chat. We will try to review this payment as soon as possible, but it can take a few hours depending on the time of day.

I see the user was already banned yesterday and the transaction updated. It's now been cancelled.
