How do I get a 4K Compatible X1 device?

Hi!

I've read that to be sent an X1 box that can operate at 4K to match two of our TV's native resolution, I would need to submit a forum post. I've spoken with a CSR on the phone to confirm the store can provide a replacement, but the store refused to provide one, telling me they do not have any in stock and can only provide me with the small XID-P boxes.

Please let me know if there is something I need to do or if someone could assist.

Thanks!
