Limited Edition H5 Xbox Controller Broke

I didn’t know if I should post this here, but I purchased a limited edition H5 Xbox One for $500. I was at BCT until 12/16. I have been playing H5 for 12 days and the fancy limited edition controller broke. My left bumper doesn’t press anymore (or should I say, un-press?). I can still get it to register if I push it down hard but it doesn’t click at all, even though it registers.

How do I get a new one?

Probably the best thing to do would be to contact the store you purchased it from, they should be able to help you out if it has broken
