Aliexpress Order Not Delivered, No Refund

My AliExpress order has a significant issue that I require assistance with. Despite the fact that the package was held up in customs and was never delivered, the seller refuses to issue a refund. When the package was delivered, the seller had already been paid, and there is currently no one to contact about the problem. The customer support team's contact information is completely useless. I need a resolution to this problem as soon as possible, as well as a refund of my money. It's very frustrating to be left without communication and with no sign of either my package or my refund. Aliexpress, Please provide a solution to this problem as soon as possible. Please send my money back as soon as possible! We are overwhelmed by your generosity and grateful.
