I lost my right AirPod how do I get another one?

Once again, follow the steps in the link I provided to order a replacement AirPod. It's all there in the link.

Here it is again: click here-> AirPods and AirPods Case Replacement - Official Apple Support

See here: link-> AirPods and AirPods Case Replacement - Official Apple Support

You gave what to who?

You'll need to provide the serial number for the case. But you will be talking to a live person when you follow the steps there and they can help you order a replacement.

Click here-> Replace a lost AirPod

That link takes you directly to Apple support to order a new AirPod.

Follow the steps in the support document linked to in my previous reply. You can request a replacement through there.
