I'm having the same issue, I sent both of my controllers to Oculus support because of problems with the thumb sticks. They replaced the right controller within a few weeks or so, but no left controller. When I email to ask them about it they do reply, but just say they are experiencing delays due to product availability or something like that each time and don't give me any more information than that. It's been about two to three months now, I wish they would have told me they had product availability delays before I send them in, I would have just kept on spraying the thumbstick with that electronic cleaner every time I play.
