Do not use. Very poor quality work. Definitely far below the PHD standard they promised. Sounded like a casual blogger who rushed to finish the job. They had to be chased to deliver on the due date and we could not believe our eyes when we read it. Very amateur writing, did not even make sense, and they did not follow the instructions for the assignment. We even supplied a video instruction on what the assignment requires. They obviously did not have the client in mind and rushed the job.
As we could not use ANY of their work (it was just bad), we asked for a refund and after 2 weeks was flatly denied.
Do not even consider this company unless you want to waste time - which you could have used to do the assignment yourself.
Be warned.
