RO139032792CN says my tracking number is invalid. How come? Should I start to worry?

"tracking number is invalid" means your seller has not shipped the goods yet. Many seller need one week to restock inventory. If you just got the number, wait one week and track again.

it's been 20 days already and passed the average and longest arrival time

but my item has been shipped 2 weeks ago. they already gave me a tracking number meaning it was already chinapost's responsibility

your seller gave you a fake number, if you purchased from ebay/aliexpress, you should open dispute against fraud.

IC for Panasonc music system

the parcel was rejected in customs. it might be a mistake. i suggest you wait 2 more weeks and see if you can get it. if not, then open dispute for lost parcel.
