He asked the PR department to issue an apology, but the content was not really an apology. Instead, it was expressing regret that the event had not been made clear.
The apology letter said that this event was a warm-up event for the mobile app. All users who participated in the event now would be given different degrees of compensation and preferential treatment according to the spending during this period of time when the mobile app was released. Furthermore, delivery during the event would be free.
As for the problem this time, they apologized. It was their first time organizing such a large-scale event and they were inexperienced, which led to so many problems. They would definitely learn from their experience and actively correct it. They would not let down the trust of the users. Please continue to trust them and they would not disappoint users in the future.
After everything was prepared, the letter was immediately sent out.
