I've had a look at the listing, and while in general I might agree with you in so far as the listed contents in your description don't include those accessories, (although, personally, as those items could be considered integral for a digital camera, I would have made a special note of the fact that they aren't included), there might be a problem here due to the images included in the listing.

Not the images of the camera, but the specs, one of which states the box contents and lists a USB cable, instruction manual and CD-ROM. For many people, the assumption would be that because these things are standard or original inclusions, and the spec images seem to indicate as such, that they are included unless noted in the listing that they are missing.
