X-3033
X did not confirm the reply, so it was not sent again
Why it happens
The connection to X dropped or timed out before X confirmed the reply, so it may or may not have reached the customer. X does not prevent duplicates, so Rabt does not send it again on its own, to avoid it arriving twice. Rabt checks X within minutes: if the reply is there it is marked sent and charged, otherwise the amount set aside goes back to the balance.
What to do
Wait a few minutes for the check. If the message is still failed, the reply did not arrive: choose “Retry” to send it.
