Just wondering if someone could help me. I ordered some animation artwork from a seller on here, which was shipped on September 4th.
Tracking number: CW740937602US
Shortcut link to tracking: https://tools.usps.com/go/TrackConfirmA ... put.action
It has been 20 days now and the status hasn't updated from Acceptance and Dispatch to Sort Facility. I'm going a bit crazy with worry =( I contacted the UK postal services and they said there's nothing I can do except ask the seller to contact USPS. I have asked but no reply so far. I have also tried calling USPS from here myself, but my phone keeps cutting out or not connecting, I just get some static noise.
I really don't want to accept that it may be lost

I was wondering if anyone might have advice on what to do. If there's anyone who could contact USPS on my behalf (I know this is asking a lot), I'd be so grateful and be willing to pay all phone charges, and even extra fee for helping me out - it's just that the contents of the parcel is more precious to me than getting my money back to some extent.
If anyone has any experience of this too, I'd be so grateful for any help.
Thank you so much for your time guys!
