New Zealand post also dates the parcel at 2020-03-11 for international departure, so where does the date 2020-04-23 come from?
And again, has mynoarcel been sent back to its sender since it was orders on 2020-02-03?

If it hs been sent back, will I be able to see this on the tracking system?

Thank you for your kind help
I’m just very confused and furious that AliExpress won’t refund my money

http://track-chinapost.com/result_china.php?order_no=LE101682382CN shows the parcel is still in Shanghai waiting for flight to NZ since April 23. it is not returned. Waiting time to Australia and NZ is quite slow since March 2020. You need some more time.

If your buyer protection is expiring, you need ask seller in aliexpress to extend the protection, if seller doesn't response, you need open dispute to aliexpress for refund.
