Controller issues, stick shift issue and now pairing issue.

I had bought the Meta Quest s3 back in December for Christmas. Within a month, my right controller had a bad stick shift that made anything unplayable. Mind you that, there wasn't any games that I had that I had to used the thumbstick for so for a component that I barely used break was awful. I had to send the controller for a replacement. It took a month for them to send back a controller with about 3-4 times contacting customer service to ask about my replacement with no answer. The only answer they gave me was "We will look into this matter" all the times I've contacted them to get any updates. This experience itself was appalling. 

Now my left controller isn't pairing to my headset. It is stuck on "Updating firmware" only for it to fail. When a prompt comes up to pair the controller, nothing happens when I hold Y and =, no vibrations, just the controller blinking. My right controller is connected just fine. I've tried hard booting, I've tried unpairing and pairing it through my phone, I've replaced new batteries, I've tried using their software update tool, I've contacted customer service and went through the steps to troubleshoot. I've spent the past 2 hours troubleshooting to no avail. Now they just want me to send it in for another replacement. This is one of the worst experience I've had with any company or products and all I can get is "I'm sorry you are having a bad experience, I understand" but the company does very little to fix the issue. I feel like as if I've been sold a very bad product and being told this is the best they can do with a cheap apology attached. 

Does anyone have a solution to this?
