Oh, bullshit. That's lint or something, and those scratches are totally normal. Buffing leaves circular scratches.
It looks better than most phones that have been in use more than a week or two.

In this case, the phone does look as if it had either a hard fall, or a hard hit against something.
In addition to the defect the guy called them about I see unscratched glass, unscratched metal, lint, and some abrasions on one of the three edges of plastic that don't go deep at all (I bet you couldn't feel them) which are probably only visible because the phone is being lit from above. None of this is a big deal.
