I loves these guys! They are fast, and affordable! We enjoyed working with them. Please don't hesitate to contact them for your processing needs! They will not disappoint!


I was a bit worried because I had an urgent need, not that much money, and a special case, but Mr. Haywood addressed everything spectacularly! Fast response times and great customer service. I've never needed a PI before, and he made navigating the process super easy and understandable. Highly recommended!

Bertha, San Antonio, TX

Excellent investigative skills. I'm an attorney who hired him to investigate issues in my client's case. Thanks to him, my client's case was won. I've continued to hire him . Highly recommend him !!!!!

The staff at On Call Investigative service was fantastic to work with. The job they did for me was above and beyond what was expected. It was a difficult case but they did not give up. Exactly what you expect from a professional. I will call them again when I need their service. Great people to work with.
