RG008027295CN was sent to airline on Jun 22. Normally parcel will arrive in about 3 to 5 weeks after sent to airline date.

RC433786722CN seems to have problem to pass security check. open a dispute and claim refund asap.

estimated, for your urgent help, make a purchase and I got the following tracking number: RB635700989CN and no trace of that number in china post.
is a parcel to Chile

You should wait 3-10 business days before results will show up in the tracking system. If the time limit passed open a dispute or claim a refund or contact the seller for a solution.

Of it's been a month since the item was shipped then open a dispute if you ordered from AliExpress or claim refund from PayPal before the purchase protection ends.

RD855787674CN is not a valid number. if the parcel is really shipped, http://track-chinapost.com/startairmail.php will show location and status within 48 hours.
