Hi, I have 2 parcels shipped from MEL australia, to Guangzhou through AUSPOST.
They have both been stuck with "item recieved into customs for clearance" since Oct 29.
Is there any further information I can find out here? A phone number I could call?
Tracking numbers:
LK219809016AU
LK219826368U

Package stuck in customs for almost 2 weeks now this was a returned item. I made a purchase on AliExpress and now I am returning it. I can’t get a refund until they get their item back. I have waited weeks for it to get to China only to be stuck in customs for weeks. USPS tracking: CH128822962US

I returned an eBay item to the seller through USPS international shipping in August 10, and now it's already September 9. The tracking number is CH074991648US.

2019-08-16 15:44, CHINA, GUANGZHOU, Held in Customs -> Your item is being held in Customs at 3:44 pm on August 16, 2019 in GUANGZHOU, CHINA.

I have read another similar case from the link. It seems not just my only case.

What really happened in customs in GUANGZHOU? I should get a refund through this return and it makes me annoyed and stressful. What do I do now? There's absolutely no way to contact customs in Guangzhou, and it would be appreciated if you let me know an email address I can reach and let me know how long I should wait more.
