2014 Cad SRX 19300994 wheel fiasco

I'm trying to order a 19300994 wheel for a 2014 Cad SRX. Of course they are on backorder. GlobalConnect (when its working) will not let me make a SPAC case. Call SPAC. Here is the conversation:
SPAC: "That part is an accessory. We can't make a SPAC case."
Me: "It is the only wheel listed to this car per the VIN."
SPAC: "Sorry. You can buy one from ADI."
Me: "No ADI on the locator shows to have it, so no, I can't."
SPAC: "Sorry. Is there anything else I can help you with"
Me: 'Nope."
I called back a second time and was told basically the same thing. Meanwhile, our customer still has a car in his shop needing a wheel.
Anyone got any ideas? Other than to run screaming out the door.
I have bills to pay.
