The lesson of case 114
Replying is not resolving. This case didn't close when Atenty answered fast (though she answered in under a minute), nor when the sofa arrived (though it arrived). It closed when the customer said it was all good — almost 23 hours after the first message, with Atenty chasing every step so the customer never had to write again.
That, multiplied by every customer who already bought from you, is Atenty's job.
