Greyhound issue?

Anyone have issues shipping items via Greyhound?

I paid for a door to be shipped from Oregon to Detroit...about 2 weeks ago.
The shipper has all paperwork that was generated on his side when he sent it. But wasn't given a Tracking Number.

Greyhound cannot find the item for me without me providing them the tracking number. Since I don't have a tracking number, I'm stuck in a viscous circle with Greyhound.

I have no reason to think the seller is being dishonest. But am curious if anyone has had issues with Greyhound shipping and how they resolved it.

Thanks
