What should I do if I do not receive a reply for a long time after sending an email to Apple Developer Technical Support ?

A week ago, I sent an email to the Apple Developer Technical Support team inquiring about technical issues. Four days ago, I received a response stating that there was no recurrence of the issue. On the same day, I supplemented the video and demo and replied to the email. As of today, it has been the fourth working day and no response has been received, which is inconsistent with the official commitment to reply to the message within three days. May I ask how to quickly advance and solve the problem?
