hi i don't know if my package has been lost, its been stuck in New York for a month without any new updates and I live in New York so I don't know why it hasn't reached me yet, my tracking number is CP418908786CN
My package RD592944475CN has been 'in-transit' since 1/6/2021 at ISC New York, NY(USPS) I contacted USPS several times and they told me that the place of origin has to provide an update since it has not been cleared at custom in the US. Please help, who should I contact to get it cleared? Or at least what steps should I ask the sender to do in China? Thank you.
What's the tracking number?
