I think this is a real picture. I can't explain the ghost finger, probably just a weird angle but it doesn't give off the generated vibe. The poster of the photo seems to be a real person as well as the person who left a comment. Probably in the OP's case the company was real but the person was impersonating. I had been involved in a couple of these scams recently and the patterns are very similar but approaches slightly different.
