The only problem I've had over the past year or two was with a headset that didn't work properly. I returned it via a UPS will pick up the box and slap on a shipping label option. They never did. But there was eventually a tracking number in the system anyway. UPS basically shrugged and said that the computer says it was picked up. But the refund went through anyway. I assume Amazon decided that UPS had picked it up and lost it.
