If you've paid — for a subscription, a balance top-up, or FBE funding — but it isn't showing on your account yet, send support a screenshot of the payment confirmation (amount, date, and transaction/reference number visible) in the chat.
Support forwards it to the finance department; these requests are normally processed within about 24 hours, and you'll get a confirmation in the same chat once the transaction has been credited to your balance.
There's no need to re-send the payment or open a new chat while it's being checked — the team updates you there once finance confirms it.
