If, for some reason, your writer didn't do the work as was required, we will provide you with revisions free of charge until you are satisfied. Provided you present us with solid reasons, you can as well ask for a different writer, or a complete rewrite. These two options, too, come for free.
The papers that you sent me Monday were GREAT!!! I reviewed them right before I turned them in and they were very very good. Tell the writer he did good!! Thanks.
