AliExpress Order Stuck at Customs - Extra Item Causing Delays

Hello, my cargo got stuck at customs due to the 5-item limitation. However, I only ordered 5 products in February, but the cargo that reached customs contained 6 items. There seems to be a problem here. I request the return of the extra product and ask AliExpress to resolve this dispute. I need guidance on how to proceed. I plan to repurchase these products from AliExpress, so returning the extra item seems like the best solution. Thank you, and I look forward to your prompt assistance. My tracking code is 2710125343538.
