I think these guys are using different tutors, sometimes they deliver well but other times for example my last exam was a mess. Kindly hire more consistent experts. To Students, There are many of these websites now and getting the right one to trust can be challenging. I am a student and I know how it feels to get scammed especially when it comes to exams. My advice is to avoid websites you are not sure about or at least take time and do a trustworthy check on Google. Personally, I use Teratutors or sometimes I go to freelance websites like Fiverr and browse for well-rated experts there. So if you are not sure use these old trusted ones, especially Teratutors because they deal directly with Academic work
