17TRACK IS A TRACKING SITE. NOT A SHIPPING/DELIVERY SERVER. Smarties.
I always use 17track to track all of my orders in one place without needing the extra headache of many different sites from different couriers. I track all my aliexpress and ebay orders with 17track. They provide a more detailed tracking and info then what official tracking number sites give. Once again, they are a TRACKING SERVICE. NOT A SHIPPING OR DELIEVERY SERVICE. They literally aren't involved in any part of your order or shipping.
