If your items have not been delivered, here are some steps to resolve the issue:
Track your package to check the shipping status. Sometimes, a tracking number may seem invalid due to late updates. If this happens, contact the seller to clarify the situation.
Contact the seller for more details. If this does not resolve the issue, consider opening a dispute to request a refund. Be sure to do this before the end of the buyer protection period.
If the buyer protection period has ended, turn to Aliexpress customer service for assistance.
