Today I ordered my first essay (well actually it was an assignment). The time frame I gave the company was 2 weeks and much to my surprise my assignment was completed in only a few hours.

I was very excited that my first experience was going so well, that is until I read my assignment.
I'm not particularly fussy, I did not expect a word document oozing academic perfection, I did however expect that the writer would have stuck to the 'criteria' of using sources from my country. Another expectation I had was that the assignment would actually make sense.
For example, an excerpt.
"Since, the article has also been drafted keeping in purpose the targeted audience and then using the proper media to communicate with them will ensure that there is maximum satisfaction and the targeted audience is appealed."I'm unsure of how to go about getting a rewrite of the assignment because as a whole it just doesn't make sense. I really don't want to be rude, difficult or fussy in any way. I don't want the writer to get in trouble or fined or fired, but I really hope that somehow I can get the assignment that I paid for.
I requested a revision and was asked to point out which parts don't make sense and the writer would revise these parts. How do I point out, kindly, that the whole thing just isn't right? Is such a reply to my revision request justified and normal under these circumstances?
