Service tech scratched my laptop

Recently a Dell service technician came to my house to replace the webcam in my laptop.  In order to do this she had to seperate the two halves of the laptop lid.  A couple of days later I noticed several scratches at the bottom of the lid on the screen side. 

What can I do to fix this?  I haven't contacted Dell about it because my guess is that nothing will be done about it.  I take good care of my computer and always keep it clean, not to mention that it was a very expensive laptop.  These scratches are really annoying me.

I have included a picture of the scratches. 

Thanks.
