Day 13, still no mattress delivery from Costco. Any similar experiences?

Hey all. On the 2nd, I bought a mattress online from Costco. There was no ETA given and the tracking information simply shows that it has arrived at a facility in SC on the 5th. (I'm in NC). Per tracking, no "target date" was given and customer service via the chat option wasn't helpful at all.

I really thought buying via Costco would be a sure-fire good experience but unfortunately the opposite has been true. Anyone else order a mattress? What was your delivery time frame? Thanks
