In my experience, this is a place where getting what you paid for, is not easy.
Update: I don't know what these people are or what they're not, but my experience is that this is one of the many nicely dressed frauds out there. The reason for my opinion are questionable competencies of the staff, who produce unreliable results that are quite possibly useless, making a customer lose two important things - time and money, don't recommend it.
