@Rashid, Sorry to say, but you cannot delete that post with the help of google (why?).
Because, I think, Google has chosen fools for this work.
Some days ago, I had reported a blog which has copied my article, widgets and all things without credits.
To help them to find that widget, I provided them the URL with id (.../...#HTMLID) but, I got the same message which you have got.
Some days ago, @Mohammad had also shared such experience in which, the whole article was copied but he got the same message.
They are not doing enough for Bloggers.
