Pam C

Dear Annex,

Thank you so much for helping me finally identify who and how has been cheating me in my business. I would not have been able to fix this matter by myself and because you have such great expertise (at) what you do, you were able to.

A whole new start is ahead of me now and I am very grateful to you.

Yours truly,


Steve Smith

Dear Annex,

A short note to thank you and your team for helping Council resolve the very difficult issues we faced with now former members of our staff. The work your investigators undertook was extraordinary and clearly showed our suspicions were correct. We very much appreciated your close liaison with us and support through a very difficult time and should the need for services of your type arise again, we won’t hesitate to contact you.
