It was a request to prevent imminent dispatch of an order to an unattended address. So it did require a timely acknowledgement from A/S.
Initial contact sent Tuesday morning, follow-up sent this morning. This afternoon as I posted, I received a request to give feedback on how my chat had been handled (before any response had been received). Hence the choice of RMWeb as the nuclear option, knowing that it would resolve the issue (which thanks to A/S's usual alertness it has), albeit stirring up the expected hornet's nest in the process.
I have attempted to change the title of the thread.....
