The support team was available upon request. For the past two semesters I have been stressing on receiving my assignments on expected achievement dates. I value your service and hope that you all would improve your teamwork. I have been using this service now for 2-years and was totally satisfied. With this being said, I have spent at least a thousand plus dollars with this company. Knowing there are other competing companies that are on the market for a lot less than you guys are charging. "I trust that you all would get it together and avoid last minute communication which increases stress to the student."
