RK470762552CN Not receive my package yet and guarantee delivery date by seller was 20 dec. what to do, should I wait or open dispute. Any estimate delivery date?

I paid expressed shipping - for my package my tracking number is AS025040969CN
And order number is : 202307259780289
I’ve been waiting and waiting days 8fays in transit now still and I’ve never seen or Ben given a delivery date approx. or anything like that and I paid extra for expressed ! I’m terribly frustrated - just trying g to find out a delivery date at least I’ve tried every app and site tracking it - I also would possibly like to pay for it to get here faster and with a time stamp to add if so defiantly - I’f possible, cheers thanks :)

I placed an order 03/02/2020
My expected delivery date was March 24 2020.
5 days after placing order expected delivery date was changed to July 05.
Now again 3 days ago changed expected delivery date to may 05.
My parcel was sent to dongguan intl. And from there scanned twice as already handed off to the airline then on the 03/10/2020 says planned handing off to airline. Like... I understand with the corona virus and airline cancels etc, but what's the back and forth stuff and delivery date changing with the yea we gave to airline but no we didnt so we now planning it stuff. I just want a valid ETA on when I can expect my parcel and what situation it is in. If it's being held due to other circumstances fine but I hate being told it's on an airplane and its really sitting in a warehouse. So yea that's my question. TY.
