Professional Surveillance on my Ex-Partner I used Private Investigator to carry out surveillance on my partner as he had started working longer hours but things weren't adding up. The reason I chose this company is because when I initially spoke to them, they seemed more friendly than other detectives that I spoke to and they answered all of my questions. My case manager was supportive before, during and after my surveillance and although I found out that my partner had had a baby with another women, I am happy that I've found out and can move on with my life. Would definitely recommend Private Investigator.
