Invited for Xbox flight when I only played on PC

I’ve been playing on PC for the past few years now, and have been only invited to PC flights since I got into the Insider program.
With the Halo Infinite Flights, I was invited to play on, well, Xbox. However, I don’t even…own an Xbox anymore.

Support has basically given me a middle finger saying they can’t change platforms and that I’ll have to suck it up.
Is there seriously nothing I can do?
