Airpod Gen 3 not getting connected to any of apple device.

I have purchased 2 year back and have used rarely for max 10 times. Now they suddenly getting disconnected and connected after connection. I need to keep charging case back button continuosly press to display in bluetooth list.It stops connection when i release back button of my case. Better to go with other brands rather than purchasing 17000 product from apple and if you go to service center they will charge service fee of 2500 minimum to just troubleshoot your issue. Wont recommend airpod to anyone better go and purchase boat if they cant provide service for 17000 product.
