I ordered a Lightweight Puffy Tote Bag 24 days ago and it still hasn't arrived, I sent an email 5 days ago and they still haven't replied to me. my tracking number is YT2435321272179751

The last information from 17 Track was:-
"2020-08-11 05:48
AUSTRALIA, local sorting centre, arrived in Australia AUSTRALIA, local sorting centre"
but there is a question mark ? saying "This number can't be found at this moment. It's not available in the carrier's system yet. Please check back later". However, I don't know who the local carrier is.
I have contacted 17Track who responded:-
------------------------------------------------------------------------------------------------------
"Dear 17TRACK user:
Hello! Thank you so much for contacting us.
According to your tracking number format (the tracking number starts with A and ends with CN), your parcel was shipped by the carrier China Post and normally will be handed over to your local carrier, but not local post office.
You need to contact your seller to confirm if there is a local tracking number and confirm who the local carrier of your parcel is.
It is the way how this kind of mail works."
-------------------------------------------------------------------------------------------
So, basically, I need to know if there is a LOCAL tracking number in Australia and who the local carrier is. Australia Post does not recognise the number..
However, Australia Post
(Auspost) says about Tracking Number: AS470264141CN:-
-----------------------------------------------------------------------------------------------------------------
That article ID is definitely not showing any information in our system. It's also quite odd as usually international tracking numbers only start with the letters U,L,C or E. I've never seen one starting with A myself.
I'd recommend letting your sender know that you haven't received your order. They'll need to follow up with China Post to find out what the situation is.

Many thanks,

Tracking number : AG983940105CN
Order number : 230628022334185
Vendor : Amandéia
Carrier : Hauntong
The tracking number of this order says that it was delivered yesterday, July 31st. The local carrier is "La Poste". This one says that the parcel is not yet on their structure, but the tracking number is recognized.
So I don't know if the tracking indicates a final delivery to the purchaser (myself) or to a local carrier other than La Poste ?
Thanks for your help.
