How do I get my elite controller series 2 replaced?

My elite series 2 rb button doesnt work and i cant find a replacement button how do i fix this

Microsoft knew the controllers were defective and still sold them as a good product. they wont do anything to fix your controller because its most like out of warranty thats why the warranty was so short. The whole elite series 2 was a scam

Turns out, the Xbox Elite Series 2 controller needed to be replaced.

I would like to get this controller repaired but I can only find ways to get a replacement. This is a xbox design lab controller so idk if they're gonna replace it, plus the serial number didnt show up when I punched it in. Is there an easier way to get a replacement or a fix for this elite series 2 controller?

I got my controller back and the left stick was still stuck. I don't know If they test the controllers(obviously not) but I do know that if they couldn't fix the controller(which they didn't) they would replace it. I didn't get a replacement, my controller wasn't repaired. An series 2 Elite controller is quite expensive I don't understand why they treat It likes it's nothing. I'm not made of money, please someone help me.
