My Left Controller won’t work the battery case won’t come out. What do I do?

After having a failing discussion with the meta support ai I’ve turned to the community. My left controller is charged 100% and won’t work with my meta quest three and neither of the controllers batteries will slide out after I’ve watched countless videos about it. I’m not sure what to do with my left controller as I’ve had it for only a year and the right one works fine. This randomly happened and I keep amazing care of it.
