Query: Didn't include software

What a nightmare. Received as a Christmas present. Opened the package....no software. Didn't come with the CD. Tried to download it from their website, and when it asked for my serial number, I looked on the device and the "S/N" was displayed, but NO SERIAL NUMBER!!! Seriously???? Amazon.com, what kind of garbage are you putting out?? I'll have to try and call the company in the morning to see if they can either walk me through a download, or send me a CD with the required software. VERY disappointed.
