1. He doesn't answer every questions, only the one he feels like
2. Very quite Responds + the work is "completed" quickly
3. Check the work, only 25% of the answers will be there the rest is not to be seen in any links he provided and claim to have answered.
4. Still a good service but I won't be ordering, too much time wasted on Unanswered questions and me having to convince the guy I can't see the answer instead of the other way around.
