Razer Wildcat Problems

Howdy Razer Support, Over the past couple of months my Razer Wildcat has started to get progressively less responsive with the RB button and the use of the left joystick. The joystick has been completely unresponsive this past week even when pushed all the way in one direction. I have tried using compressed air to clean everything out, reset the controller, reset the Xbox--all to no avail. I've had it since June of 2018 and put probably thousands of hours into it, but I was wondering if there was anything I could do to get it fixed or repaired since it is out of warranty. Really grown accustomed to this controller and any other really just doesn't feel as right. Thank you in advance. Respectfully, Geoff
