ALERT!! SOUND THE ALARM!!..
I’m not clear on why you haven’t gotten the other stuff yet.
At this point I’d say, if they can’t ship everything other than the rockers today......... I’d cancel the whole order.
Actually....... if you didn’t have a specific build in mind for the parts, and just bought them because it was cheap........for a yet to be determined project........ I might be tempted to just cancel it all as a matter of principle.
