Mystery is solved! I have tell you, we have a fantastic sheriff department here. Here's the story.....
The USPS had a GPS on where my gift card was delivered. It was either at an older lady's house or a small business across the road. The post office went to the small business and asked them if they received it, and they said no, so the post master thought it must have been delivered to the older lady's home. When I filed the police report, the sheriff went to the older lady's home and quickly decided it wasn't her. The sheriff went back to the small business and asked them if they knew anything about my gift card. At that time, the owner said, "Are you talking about an Amazon gift card? Yes, I got one in the mail. I thought my wife ordered it, and I used it". The sheriff asked him if he noticed the balloon card or the fact that it said "Happy Birthday" on the card. The guy didn't have a response to that. The sheriff contacted me and asked if I wanted to press charges, and I said no, I just want my money back, which he got and delivered back to me. So, all is done and I have my money back. I'm still not sure why that guy thought he could just use it without getting caught. This is definitely a crime that is easily traceable. But, I'm so happy that this is done and over. I learned two things through this - 1) There is NO protection when ordering gift cards in the mail, and 2) I should have contacted Amazon and cancelled that card the SECOND it wasn't in my mailbox. Amazon said the card was used quickly, but they didn't say how fast. I'm just glad all this is over!
