My package CY015115203CN has not updated for 60 days. Normally, I'd think that this was due to delays, but this is the second half of one giant order I purchased. The first half, which was sent at the same time, has already arrived and updated regularly. This one has been stuck on "leaving the post office" for so long that I think it's lost. I've tried contacting the seller, but they just say they're contacting the shipping agent over and over again. Is there anything else I can do?

Tracking number: AT356551078CN

Tracking hasn’t updated for 19 days. Is the package lost or will I receive it? Last update was departure from processing centre in dongguan on 3rd April. Im worried now

My package LY852799486CN from China has not been updated since August 20. It is now almost been a week and nothing has updated with the parcel information. Any advice?
