DHL Tracking Stuck and Still No Delivery After 26 Days for My Amazon Order

I placed an order for a model kit on Amazon from a Chinese seller on 06/07/2024. The item was shipped within 2 days, and everything seemed fine initially. However, when I tracked the package through Amazon, it only said "in transit," even after a week. I then entered the tracking number on DHL's website and saw that the last update said "DGF Star Broker, UK." It's now been 26 days, and I still haven’t received my package. There have been no further updates, and I’m left wondering where my order is. I need assistance in resolving this delay, as it’s been far too long without any proper tracking information or delivery.
