I can truly say that I have received a 100% service. Jack took the time to call me. He was polite, courteous and attentive to my needs. The best type of service for my needs and within no more than a few hours I had a full report, if you ever need a private investigating service, I would encourage you to use National Private Investigators. Thank you, Jack and your team.
