First of all, once you opt for their services, you don't know how much will you be charged. Secondly, the answers were not explained. If you ask them if you could reach out to the teacher who did it and get explanations or correct the work, they say no. They will threat you if you argue with them, they will say we will go to your university or call the cops as they keep confidential information like your address with them. Work is of poor quality, instructions were not followed. They Don't give you a timeframe either so better off not to take their services.
