Hello, We're sorry you had an unpleasant experience. For this order, we strictly followed the DDP terms you specified and the agreed air shipping by UPS(10-15 days after plane departure) Before payment, we clearly informed you about the timeline and tracking rules. The 5-day May Day public holiday affected the schedule, but we still delivered on May 19th after the flight took off on May 10th, all as planned. We provided the tracking number and logistic progress promptly. With air shipping, logistics information only shows up after customs clearance. Despite we explained multiple times, still the misunderstandings occurred during communication. We're sorry if our tone was off under stress. We always operate with integrity and have retained all relevant logistics and communication records. Now you've received goods, if there are any product related issues, we're ready to assist. To other buyers, we'll ensure clear and transparent service explanations to ensure smooth cooperation.
