Because writing a dissertation is not a once-off procedure but rather one that involves multiple modifications, revisions and editing, the writing service you hire must pledge that the final document will have been prepared to your satisfaction. The firm should therefore have no compunctions about revising your paper multiple times. If the work is still not up to the required standard you should be able to get a complete fee refund. This revision policy is only possible for 14 days after the submission of the first copy of your paper. Additional information from previous order instructions will consequently call for additional payment.
