I'm not a judge, but if I were to bet on what happened this would be it.

The OP and his wife wanted a camera, the OP wanted to buy it on the Fire and show his wife what a good place it was to buy sh*t, the OP's wife didn't really want to do it, but initially gave in. When the camera showed up and it wasn't what she really wanted, she pitched a bitch. The OP then had to come up with a reason to send it back. He sent a PM claiming some BS, it pissed the seller off. Then the seller f*cked up big time by not returning he PM right away.

That about right?
