Confused. Buyer is trying to return a faulty Garmin Forerunner GPS sports watch but keeps getting the message ’item is non-returnable’. He’s not out of time/policy so he should be able to do a return request. He’s tried both through the app and using a browser but cannot do the return request no matter how much he tries. I cannot fathom why he should be presented with this message/error, I’ve had a buyer return for a fitness watch in the post and should in no way be classed as a non-returnable item. Any thoughts?
